Input for buffers

Tri-states all outputs when held LOW. Has internal pull-up.2

Data pin for I2C circuitry3

Clock pin for I2C circuitry3

PWR 3.3V Power supply for OUTPUT buffers

PWR Ground for OUTPUT buffers

PWR 3.3V Power supply for I2C circuitry and internal logic

PWR Ground for I2C circuitry and internal logic

Notes:

1.

At power up all ten OUTPUTs are enabled and active.

2.

OE has a 100K Ohm internal pull-up resistor to keep all outputs active.

3.

The SDATA and SCLK inputs both also have internal pull-up resistors with values above 100K Ohms as well for

complete platform flexibility.

Power Groups

VDD (0:5), GND (0:5) = Power supply for OUTPUT buffer
