Overview
The TCA9534 is a 16-pin device that provides 8-bit general-purpose parallel input and output (I/O) expansion for the two-wire bidirectional I²C bus (or SMBus) protocol. The device can operate over a power supply voltage range of 1.65V to 5.5V, allowing the use of various devices. The device supports clock frequencies of 100kHz (Standard Mode) and 400kHz (Fast Mode). When additional I/O is required for switches, sensors, buttons, LEDs, fans, and other similar devices, an I/O expander such as the TCA9534 provides a simple solution. Features of the TCA9534 include interrupt generation on the INT pin. This allows the host device to know when an input port has changed state. The hardware-addressable pins A0, A1, and A2 allow up to eight TCA9534 devices on the same I²C bus. The device can also be powered by cycling the power supply to generate a power-on reset, which resets the device to its default state.
