Input for buffers
Data pin for I²C circuitry³
Clock pin for I²C circuitry³
3.3V Power supply for OUTPUT buffers
Ground for OUTPUT buffers
3.3V Power supply for I²C circuitry and internal logic

Notes:
1.
At power up all thirteen 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 have internal pull-up resistors with values above 100K Ohms.
