Texas Instruments PCA9554PWG4 is an 8-bit I/O expander designed for I2C and SMBus interfaces, operating at clock frequencies up to 400 kHz. This device features a Power-On Reset (POR) circuit and provides eight push-pull I/O pins with selectable output drive strengths, capable of sourcing 10mA and sinking 25mA. An interrupt output is available for event notification. The PCA9554PWG4 is housed in a 16-TSSOP package, suitable for surface mounting. It operates across a voltage supply range of 2.3V to 5.5V and an industrial temperature range of -40°C to 85°C. This component is commonly utilized in industrial automation, consumer electronics, and communication systems requiring flexible I/O expansion.
