PCA9554

8-bit I2C and SMBus I/O Port

PCA9554 Features

* an active low interrupt output which indicates to the system master that an input state has changed. The device’s extended addressing capability allows up to 8 devices to share the same bus. Features

* 400 kHz I2C Bus Compatible (Note 1)

* 2.3 V to 5.5 V Operation

* Low Stand

PCA9554 General Description

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. The PCA9554 co.
