CAT9555, 16-Bit I2C and SMBus I/O Port
The CAT9555 is a CMOS device that provides 16 *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.
