8-bit I2C And SMBus I/O Port With Interrupt

The CAT9554 and CAT9554A are CMOS devices that provide 8-bit parallel input/output port expansion 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 CAT9554 9554A consist of an input port Register an output port Register a configuration Register a polarity inversion Register and an I2C SMBus- compatible serial Interface By Catalyst Semiconductor
