The PCA9554ARGTR from Texas Instruments is an 8-bit remote I/O expander designed for I2C and SMBus communication. Operating within a voltage range of 2.3V to 5.5V, this device offers a 400kHz fast I2C bus interface, enabling efficient expansion of microcontroller I/O capabilities.
Key features include an open-drain active-low interrupt output, input/output configuration registers, and polarity inversion registers. At power-on, all I/Os are configured as inputs with a weak pull-up. The system master can configure these I/Os as either inputs or outputs by writing to the I/O configuration bits. The device supports up to eight devices on the I2C/SMBus via three hardware address pins.
This I/O expander is housed in a 16-VQFN (3x3) package and is suitable for surface mount applications. It operates reliably within an ambient temperature range of -40°C to 85°C. The PCA9554ARGTR also boasts 5V tolerant I/Os and latched outputs with high-current drive capability for directly driving LEDs.
