Quasi-Output Structure:

- Strong PMOS transistor is turned on only during the LH transition and turned off during static drive

- Weak pull-up current source (100μA) at the output

- Used in low-power applications where the 100-μA drive is sufficient to bias the inputs of CMOS devices

- May be reconfigured as an input or output without the need of a port configuration register

Totem-Pole Output Structure:

- Upper PMOS transistor is turned on during LH transition and static high drive. Up to 10mA (or 25mA) of high drive

- Some devices have weak pull-up resistors at the output

- Used in applications requiring high drive for heavy loads

- Extra command byte needed to switch an I/O pin between input and output

Why Special Buffers on I2C-Bus ? The I2C-bus assumes the possibility of

simultaneous bi-directional signal flows.

– Without any buffers, the bus wires are

clearly bi-directional.

Conventional buffers only handle signals

traveling in one direction at any one time.

– There are logic buffers with a

direction control pin, but at any one

time they are uni-directional.

Buffers for use on an I2C-bus must not have

any pull-up capability. They must have

open-collector or open drain outputs.

If two conventional logic buffers are

connected as shown then they will simply

latch to the LOW state the first time either

side goes LOW.

– The logic symbol represents a non-

inverting, open drain, buffer.

If side A is externally pulled LOW, then the upper

open drain buffer pulls the bus at side B to the

LOW level.

With this LOW now on side B, the lower buffer will

pull side A LOW and even if the external drive at A

is removed the buses at A and B will simply remain

latched LOW.

A special type of buffer is required for I2C-bus.

48

I2C


Types of I2C-Bus Buffers

Characteristics: • A dynamic third logic level is

introduced by adding an

incremental offset voltage

to the input

• Either bus will be driven

(down), by a voltage

follower, to a level 100mV

higher than the voltage level

of the other bus

Characteristics: • Buffer automatically changes

direction in response to the

applied drive signal

• For use on SDA line ONLY

• Buffer output has “no offset”

and pulls its output down

very close to 0V

Characteristics: • A fixed third logic level is

introduced on the special I/O

side

• The third logic level is higher

(static offset) than 0.4V, but

low enough to still be a low

to the other devices on the

bus

No Offset Incremental Offset Static Offset

Characteristics: • The bus current is

amplified, but in only one

signal direction

• Current gain enables a 3-mA

driver on the input side to

drive a bus with 30-mA pull-

up on the other side

Amplifier

I2C


Pros & Cons of Different Types of Buffers NO OFFSET

• Both I/Os pull-down to zero volts for full level swing and best

• Noise margin on output side

• Both inputs interface with any slave and with most buffers

• Only used on SDA due to glitch during auto reversing

• Only class that doesn’t support clock stretch or multi-master because

SCL buffer is unidirectional

• User required to design Master’s timing to accommodate buffer and

any system delays

INCREMENTAL OFFSET

• Good VOL as long as VIL is low enough

• Can be used in series or parallel

• Supports logic level shifting

• Only type where both I/Os can be fully I2C compliant

• Offsets add up as parts are placed in series

HYBRID INCREMENTAL OFFSET

• Good VOL as long as VIL is low enough

• Variety of parts available including parts with special features such as

rising edge accelerators, precharge, and current source pull-up

• Offsets add up as parts are placed in series

• Can only be used for level shifting when part uses dual power supplies

• VIL requirement restricts the bus low voltage

STATIC OFFSET

• Strong drive down to VOL (~0.6 V)

• Wide range of single and hub parts with special features and options -

offset voltage, drive strength, over-voltage tolerance, offset on only one

side or all sides

• Work with any slave when bus low voltage is acceptable

• Forces a restrictive low bus voltage requirement on the static offset

side

• Side using offset generally cannot interface with other buffers

AMPLIFIER

• Allows driving high capacitance (~4000 pF) with low value pull-up

resistors

• Strong drive (30mA)

• No input level switch points

• No enable

• Not over-voltage tolerant

• Input not isolated from output

54

Features

“Regenerating” bi-directional SDA and SCL buffers with 1.8 – 10V bus range (device supply 2.7 – 5.5V) that can be used in series

Impose minimal system design restrictions

No rise time accelerators which might cause glitch

New Devices: – PCA9522 supports 1MHz I2C Fast-mode (6 mA)

includes hot swap logic

Applications

Multiple bus buffers needed for capacitance isolation and to buffer the I2C signals from board to board with connectors.

Voltage level translation between a 1.8V or 2.5V bus and a 3.3V or 5V bus.

When the system is fully loaded, some of the buffers are connected in series and the architecture is such that static offset bus buffers can’t be used

The clock signal has to be bidirectional, so no offset bus buffers can’t be used.
