Description: 16-Bit I2C and SMBus I/O Port

Features

* an active low interrupt output which indicates to the system master that an input state has changed. The three address input pins provide the device’s extended addressing capability and allow up to eight devices to share the same bus. The fixed part of the I2C slave address is the same as the CAT955

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 CAT9555 consists of two 8
* bit Configuration ports (input or output), Input, Output and Polarity inversion registers, and an I2C/SMBus
