The PCA9554 is an 8-bit I¬=C-bus and SMBus I/O port expander designed for applications requiring additional GPIO. It operates within a supply voltage range of 2.3V to 5.5V and supports a clock frequency of up to 400kHz. The device features eight configurable I/O pins, which default to input mode, and includes a polarity inversion register for active HIGH or LOW operation. An open-drain interrupt output signals changes in input states, enhancing system responsiveness. The PCA9554 is housed in a 16-pin SOIC package and is compatible with the PCF8574 series, although software modifications are necessary due to its enhanced capabilities. It also offers ESD protection exceeding 2000V HBM and is compliant with AEC-Q100 for automotive applications. This product is suitable for various applications, including sensors, switches, and LED control.
