Description:

8-Bit I2C and SMBus I/O Port

Features

* I 400kHz I2C bus compatible
* I 2.3V to 5.5V operation I Low stand-by current I 5V tolerant I/Os I 8 I/O pins that default to inputs at power-up I High drive capability I Individual I/O configuration I Polarity inversion register I Active low interrupt output I Internal power-on reset I No glitch

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/SMBu
