General Description

The CAT9534 is an 8-bit parallel input/output port expander for I²C and SMBus compatible applications.

These I/O expanders provide a simple solution in applications where additional I/Os are needed: sensors, power switches, LEDs, pushbuttons, and fans.

The CAT9534 consists of an input port register, an output port register, a configuration register, a polarity inversion register and an I²C/SMBus-compatible serial interface.
