Additional preview pages of the PCA9554 datasheet.

The PCA9554 is a CMOS device that provides 8

bit parallel input/output port expansion for I2C and SMBus compatible applications.

This I/O expander provides a simple solution in applications where additional I/Os are needed: sensors, power switches, LEDs, pushbuttons, and fans.
