~~I"'JXI~~I +5V-Powered, Multichannel RS-232
Drivers/Receivers ____________ ~GeneraIOescription The MAX220--MAX249 family of line drivers/receivers is intended for all EINTIA-232E and V.28/V.24 communications interfaces, particularly applications where ± 12V is not available. These parts are especially useful in battery-powered systems, since their low-power shutdown mode reduces power dissipation to less than 5/lW. The MAX225, MAX233, MAX235, and MAX245/MAX246/MAX247 use no external components and are recommended for applications where printed circuit board space is critical.

______ Detailed Description The MAX220-MAX249 contain four sections: dual charge-pump DC-DC voltage converters, RS-232 drivers, RS-232 receivers, and receiver and transmitter enable control inputs.
Dual Charge-Pump Voltage Converter The MAX22~MAX249 have two internal charge-pumps that convert +5V to ±10V (unloaded) for RS-232 driver operation. The first converter uses capacitor C1 to double the +5V input to +1 OV on C3 at the V + output. The second converter uses capacitor C2 to invert + 1 OV to -10V on C4 at the V- output.
A small amount of power rnay be drawn from the + 10V (V+) and -10V (V-) outputs to power extemal Circuitry (see the Typical Operating Characteristics section), except on the MAX225 and MAX245-MAX247, where these pins are not available. V+ and V- are not regulated, so the output voltage drops with increasing load current. Do not load V+ and V- to a point that violates the minimum ±5V EIA/TIA-232E driver output voltage when sourcing current from V+ and V- to external circuitry.
When using the shutdown feature in the MAX222, MAX225, MAX230, MAX235, MAX236, MAX240, MAX241 , and MAX245-MAX249, avoid using V+ and Vto power external circuitry. When these parts are shut down, V- falls to OV, and V+ falls to +5V. For applications where a + 10V external supply is applied to the V+ pin (instead of using the internal charge pump to generate + 10V), the C1 capacitor must not be installed and the SHDN pin must be tied to Vee. This is because V+ is internally connected to Vee in shutdown mode.
RS-232 Drivers The typical driver output voltage swing is ±8V when loaded with a norninal 5kU RS-232 receiver and Vee = +5V. Output swing is guaranteed to meet the EIAffIA-232E and V.28 specification, which calls for ±5V minimum driver output levels under worst-case conditions. These include a minimum 3kn load, Vee = +4.5V, and maximum operating temperature. Unloaded driver output voltage ranges from (V+ -1.3V) to (V- +O.5V).
Input thresholds are both TIL and CMOS compatible. The inputs of unused drivers can be left unconnected since 400kO input pull-up resistors to Vee are built in (except for the MAX220). The pull-uP reSistors force the outputs of unused drivers low because all drivers invert. The intemal input pull-up reSistors typically source 121JA, except in shutdown mode where the pull-ups are disabled. Driver outputs turn off and enter a high-impedance state-where leakage current is typically microamperes (maximum 25iJA)-when in shutdown
14
mode, in three-state mode, or when device power is removed. Outputs can be driven to ±15V. The powersupply current typically drops to 81JA in shutdown mode. The MAX220 does not have pull-up resistors to force the outputs of the unused drivers low. Connect unused inputs to GND or Vee.
The MAX239 has a receiver three-state control line, and the MAX223, MAX225, MAX235, MAX236 , MAX240, and MAX241 have both a receiver three-state control line and a low-power shutdown control. Table 2 shows the effects of the shutdown control and receiver threestate control on the receiver outputs.
The receiver TIL/CMOS outputs are in a high-impedance, three-state mode whenever the three-state enable line is high (for the MAX225/MAX235/MAX236/MAX239-MAX241), and are also high-impedance whenever the shutdown control line is high.
When in low-power shutdown mode, the driver outputs are turned off and their leakage current is less than 1iJA \..,ith the driver output pulled to ground. The driver output ~eakage remains less than 1iJA, even if the transmitter output is backdriven between OV and (Vee + 6V). Below -0.5V, the transmitter is diode clamped to ground with 1kO series impedance. The transmitter is also zener clamped to approximately Vee + 6V, with a series impedance of 1 kO.
The driver output slew rate is limited to less than 30V /iJS as required by the EINTIA-232E and V.28 specifications. Typical slew rates are 24V/iJs unloaded and 10V/iJs loaded with 30 and 2500pF.
R5-232 Receivers EIAffIA-232E and V.28 specifications define a VOltage level greater than 3V as a logic 0, so all receivers invert. Input thresholds are set at 0.8V and 2.4V, so receivers respond to TIL level inputs as well as EIAffIA-232E and V.28 levels.
The receiver inputs withstand an input overvoltage up to ±25V and provide input terminating resistors with

nominal 5k.Q values. The receivers implement Type 1 interpretation of the fault conditions of Y.28 and EINTIA-232E.
The receiver input hysteresis is typically 0.5Y with a guaranteed minimum of 0.2Y. This produces clear output transitions with slow-moving input signals. even with moderate amounts of noise and ringing. The receiver propagation delay is typically 600ns and is independent of input swing direction.
Low-Power Receive Mode The low-power receive-mode feature of the MAX223. MAX242. and MAX245-MAX249 puts the IC into shutdown mode but still allows it to receive information. This is important for applications where systems are periodically awakened to look for activity. Using low-power receive mode. the system can still receive a Signal that will activate it on command and prepare it for communication at faster data rates. This operation conserves system power.
Negative Threshold-NIAX243 The MAX243 is pin compatible with the MAX232A. differing only in that RS-232 cable fault protection is removed on one of the two receiver inputs. This means that control lines such as CTS and RTS can either be driven or left floating without interrupting communication. Different cables are not needed to interface with different pieces of equipment.
The input threshold of the receiver without cable fault protection is -0.8Y rather than + 1 .4Y. Its output goes positive only if the input is connected to a control line that is actively driven negative. If not driven. it defaults to the 0 or "OK to send" state. Normally. the MAX243's other receiver (+ 1.4Y threshold) is used for the data line (TO or RD). while the negative threshold receiver is connected to the control line (DTR. DTS. CTS. RTS. etc.).
Other members of the RS-232 family implement the optional cable fault protection as specified by EINTIA-232E specifications. This means a receiver output goes high whenever its input is driven negative. left floating. or shorted to ground. The high output tells the serial communications IC to stop sending data. To avoid this. the control lines must either be driven or connected with jumpers to an appropriate positive voltage level.

Shutdo~22-MAJC242 On the MAX222. MAX235. MAX236. MAX240. and MAX241. all receivers are disabled during shutdown. On the MAX223 and MAX242. two receivers continue to operate in a reduced power mode when the chip is in shutdown. Under these conditions. the propagation delay increases to about 2.5/Js for a high-to-Iow input transition. When in shutdown, the receiver acts as a CMOS inverter with no hysteresis. The MAX223 and MAX242 also have a receiver output enable input (EN for the MAX242 and EN for the MAX223) that allows receiver output control independent of SHDN (SHDN for MAX241). With all other devices, SHDN (SHDN for MAX241) also disables the receiver outputs.
The MAX225 provides five transmitters and five receivers, while the MAX245 provides ten receivers and eight transmitters. Both devices have separate receiver and transmitter-enable controls. The charge pumps turn off and the devices shut down when a logic high is applied to the ENT input. In this state, the supply current drops to less than 25/JA anp the receivers continue to operate in a low-power receive mode. Driver outputs enter a high-impedance state (three-state mode). On the MAX225, all five receivers are controlled by the ENR input. On the MAX245, eight of the receiver outputs are controlled by the ENR input. while the remaining two receivers (RA5 and RB5) are always active. RA1-RA4 and RB1-RB4 are put in a three-state mode when ENR is a logic high.
Receiver and TransmiHer Ena"Ie Control Inputs
The MAX225 and MAX245-MAX249 feature transmitter and receiver enable controls.
The receivers have three modes of operation: full-speed receive (normal active), three-state (disabled), and lowpower receive (enabled receivers continue to function at lower data rates). The receiver enable inputs control the full-speed receive and three-state modes. The transmitters have two modes of operation: full-speed transmit (normal active) and three-state (disabled). The transmitter enable inputs also control the shutdown mode. The device enters shutdown mode when all transmitters are disabled. Enabled receivers function in the low-power receive mode when in shutdown.

+5V.Powered, Multichannel RS·232 Drivers/Receivers Tables 1a-1d define the control states. The MAX244 has no control pins and is not included in these tables.
The MAX246 has ten receivers and eight drivers with two control pins, each controlling one side of the device. A logic high at the A-side control input (ENA) causes the four A-side receivers and drivers to go into a three-state mode. Similarly, the B-side control input (ENB) causes the four B-side drivers and receivers to go into a three-state mode. As in the MAX24S, one Aside and one B-side receiver (RAS and RBS) remain active at all times. The entire device is put into shutdown mode when both the A and B sides are disabled (ENA = ENB = +SV).
The MAX247 provides nine receivers and eight drivers with four control pins. The ENRA and ENRS receiver enable inputs each control four receiver outputs. The ENT A and ENTB transmitter enable inputs each control four drivers. The ninth receiver (RSS) is always active. The device enters shutdown mode with a logic high on both ENTA and ENTB.
The MAX248 provides eight receivers and eight drivers with four control pins. The ENRA and ENRB receiver enable inputs each control four receiver outputs. The ENTA and ENTB transmitter enable inputs control four drivers each. This part does not have an always-active receiver. The device enters shutdown mode and transmitte~into a three-state mode with a logic high on both ENT A and ENTB.
16
The MAX249 provides ten receivers and six drivers with four control pins. The ENRA and ENRS receiver enable inputs each control five receiver outputs. The ENT A and ENTB transmitter enable inputs control three drivers each. There is no always-active receiver. The device enters shutdown mode and transmitters go into a three-state mode with a logic high on both ENTA and ENTB. In shutdown mode, active receivers operate in a low-power receive mode at data rates up to 20kbits/sec.
____ Applications Information Figures S through 2S show pin configurations and typical operating circuits. In applications that are sensitive to power-supply noise, VCC should be decoupled to ground with a capacitor of the same value as C1 and C2 connected as close as possible to the device.

LM124/LM224/LM324/LM2902 Low Power Quad Operational Amplifiers General Description The lM124 series consists of four independent, high gain, intemally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of votlages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage.
Application areas include transducer amplifiers, DC gain blocks and all the conventional op amp circuits which now can be more easily implemented in single power supply systems. For example, the lM124 series can be direcUy operated off of the standard +5V power supply votlage which is used in digital systems and will easily provide the required interface electronics without requiring the additional ±lSV power supplies.
Unique Characteristics • In the linear mOde the input common-mode voltage
range indudes ground and the output voltage can also swing to ground, even though operated from only a single power supply voltage
• The unity gain cross frequency is temperature compensated
• The input bias current is also temperature compensated
Connection Diagram
Advantages • Eliminates need for dual supplies • Four intemaNy compensated op amps in a single
package • Allows direCtly sensing near GND and VOUT also goes
toGND • Compatible with an forms of logic • Power drain suitable for battery operation
Features • Intemally frequency compensated for unity gain • large DC voltage gain 100 dB • Wide bandwidth (unity gain) 1 MHz
(temperature compensated) • Wide power supply range:
Single supply 3V to 32V or dual supplies ± 1.SV to ± 16V
• Very low supply current drain (700 ~A)-essentially independent of supply voltage
• Low input biasing current 45 nA (temperature compensated)
• low input offset voltage 2 mV and offset curren!: 5 nA
• Input common-mode voltage range indudes ground • Differential input voltage range equal to the power
supply voltage • large output voltage swing OV to V· - 1.SV

Note4: For operating at high temperatures. the LM3241LM324A1LM2902 must be derated based on a +125"C maximum junction temperature and a thennal rests-tance of sa"C/W which applies for the device soldered in a printed circuit board, operating in a still air ambient. The LM224J1...M224A and LM1241LM124A can be de-rated based on a +150'C maximum junction temperature. The dissipation is the total of all four amplifiers-use external resistors, where possible. to allow the am-plifier to saturate of to reduce the power which is dissipated in the integrated circuit
Note 5: Short circuits from the output to y+- can cause excessive heating and eventua.t destruction. When considering short drcuits to ground, the ma.ximum output current is approximately 40 rnA independent of the magnitude of y+. At values of suppty voltage in excess of +15V, continuous short-cin::uits can exceed the power
dissipation ratings and cause eventual destruction. Destructive dissipation can result from simultaneous shorts on all ampflfiers.
Note 6: This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the rollector--base jwlction of the input PNP tran-sistors beroming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is also lateral NPN parasitic transistor action on the Ie chip. This: transistor action can cause the ou1put voftages of the op amps to go to the v+voftage level (or to ground for a large overdrive) for the time duration that an input is driven negative. This is not destructive and nonnal output states wiD re-establish when the input voltage, which was negative, again returns to a value greater than -O.3V (at 25"C).
Note 7: These specifications are limited to -55"C s: T AS: +12S"C forthe LM124/LM124A With the LM2241LM224A, aU temperature specifications are limited to -25-C :5 TA :5 +B5'C, the LM3241lM324A temperature specifications are limited to O'C s TA S +70·C, and the LM2902 spedfications are limited to -40·C:s TA s +SS·C.
Note 8: Vo "" 1.4V, Rs = on wrth y+ from 5V to 3OV; and over the full input rommon~mode range (OV to y+ - 1.5V) for LM2902, y+ from 5V to 26V.
Note 9: The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant. independent of the state of the output so
no loading change exists on the input lines.
Note 10: The input cornmon-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V (at 2S·C). The upper end of the common~rnode voftage range is y+ - 1.5V (at 25'C), but either or both inputs can geta +32V without damage (+26V forLM29(2), independent of the magnitude of
V'. Note 11: Due to proximity of external components, insure that ooupling is not originating via stray capacitance between these external parts. This typically can be detected as this type of capacitance increases at higher frequencies.
Note 12: Refer to RETS124AX for LM124A military spedfications and refer to RETS124X for LM124 military specifications.
