The TCA9554A is a 16-pin device that provides 8 bits of general purpose parallel input-output (I/O) expansion for the two-line bidirectional I2C bus (or SMBus) protocol. The device can operate with a power supply voltage ranging from 1.65 V to 5.5 V. The device supports both 100-kHz (Standard-mode) and 400-kHz (Fast-mode) clock frequencies. I/O expanders such as the TCA9554A provide a simple solution when additional I/Os are needed for switches, sensors, push-buttons, LEDs, fans, and other similar devices.

The features of the TCA9554A include an interrupt that is generated on the INT pin whenever an input port changes state. The A0, A1, and A2 hardware selectable address pins allow up to eight TCA9554A devices on the same I2C bus. The device can also be reset to its default sate by cycling the power supply and causing a power-on reset.
