9 Detailed Description

9.1 OverviewThis 16-bit edge-triggered D-type flip-flop is designed for 1.65-V to 3.6-V VCC operation.

A buffered output-enable (OE) input can be used to place the eight outputs in either a normal logic state (high orlow logic levels) or the high-impedance state. In the high-impedance state, the outputs neither load nor drive thebus lines significantly. The high-impedance state and increased drive provide the capability to drive bus lineswithout interface or pull-up components.

OE does not affect internal operations of the flip-flop. Old data can be retained or new data can be entered whilethe outputs are in the high-impedance state.

To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-upresistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator ina mixed 3.3-V/5-V system environment.

Active bus-hold circuitry holds unused or not driven inputs at a valid logic state. Use of pull-up or pull-downresistors with the bus-hold circuitry is not recommended.

The SN74LVCH16374A is particularly suitable for implementing buffer registers, I/O ports, bidirectional busdrivers, and working registers. It can be used as two 8-bit flip-flops or one 16-bit flip-flop. On the positivetransition of the clock (CLK) input, the Q outputs of the flip-flop take on the logic levels set up at the data (D)inputs.

This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs,preventing damaging current backflow through the device when it is powered down.

9.3 Feature Description• Wide operating voltage range

– Operates from 1.65 V to 3.6 V• Allows down voltage translation

– Inputs accept voltages to 5.5 V• Ioff feature

– Allows voltages on the inputs and outputs when VCC is 0 V• Bus Hold on data inputs eliminates the need for external pull-up or pull-down resistors

10 Application and Implementation

NOTEInformation in the following applications sections is not part of the TI componentspecification, and TI does not warrant its accuracy or completeness. TI’s customers areresponsible for determining suitability of components for their purposes. Customers shouldvalidate and test their design implementation to confirm system functionality.

10.1 Application InformationThe SN74LVCH16374A device is a high-drive CMOS device that can be used for a multitude of bus-interfacetype applications where the data needs to be retained or latched. The SN74LVCH16374A device can produce 24mA of drive current at 3.3 V; thus, making it ideal for driving multiple outputs and appropriate for high-speedapplications up to 150 MHz. The inputs are 5.5-V tolerant allowing it to translate down to VCC. The Ioff featureallows voltages on the inputs and outputs when VCC is 0 V. The Bus Hold feature eliminates the need for externalpull-up or pull-down resistors on unused or floating inputs.

10.2 Typical Application

Figure 5. Typical Application Schematic

10.2.1 Design RequirementsThis device uses CMOS technology and has balanced output drive. Care should be taken to avoid buscontention because it can drive currents that would exceed maximum limits. The high drive will also create fastedges into light loads, so routing and load conditions should be considered to prevent ringing.

10.2.2 Detailed Design Procedure1. Recommended input conditions

– Rise time and fall time specs: See (Δt/ΔV) in the Recommended Operating Conditions table.– Specified High and low levels: See (VIH and VIL) in the Recommended Operating Conditions table.– Inputs are overvoltage tolerant allowing them to go as high as 5.5 V at any valid VCC.

2. Recommend output conditions– Load currents should not exceed 50 mA per output and 100 mA total for the part.– Outputs should not be pulled above VCC.

11 Power Supply RecommendationsThe power supply can be any voltage between the MIN and MAX supply voltage rating located in theRecommended Operating Conditions table.

Each VCC pin should have a good bypass capacitor to prevent power disturbance. For devices with a singlesupply, 0.1 μF bypass capacitor is recommended. If there are multiple VCC pins, 0.01 μF or 0.022 μF isrecommended for each power pin. It is acceptable to parallel multiple bypass capacitors to reject differentfrequencies of noise. A 0.1 μF and 1 μF are commonly used in parallel. The bypass capacitor should be installedas close to the power pin as possible for best results.

12 Layout

12.1 Layout GuidelinesWhen using multiple bit logic devices inputs should not ever float.

In many cases, functions or parts of functions of digital logic devices are unused, for example, when only twoinputs of a triple-input AND gate are used or only 3 of the 4 buffer gates are used. Such input pins should not beleft unconnected because the undefined voltages at the outside connections result in undefined operationalstates. Specified in Figure 7 are the rules that must be observed under all circumstances. All unused inputs ofdigital logic devices must be connected to a high or low bias to prevent them from floating. The logic level thatshould be applied to any particular unused input depends on the function of the device. Generally they will betied to GND or VCC; whichever makes more sense or is more convenient. It is generally acceptable to floatoutputs unless the part is a transceiver unless the part has bus hold.
