Part CAT9555
Description 16-Bit I2C and SMBus I/O Port
Feature CAT9555 16-bit I2C and SMBus I/O Port w ith Interrupt Description The CAT9555 i s a CMOS device that provides 16−bit parallel input/output port expansion fo r I2C and SMBus compatible applications .
These I/O expanders provide a simple solution in applications where addition al I/Os are needed: sensors, power swit ches, LEDs, pushbuttons, and fans.
The CAT9555 consists of two 8−bit Configu ration ports (input or output), Input, Output and Polarity inversion registers , and an I2C/SMBus−compatible serial interface.
Any of the sixteen I/Os can be configured as an input or output by writing to the confi .
