IC I/O EXPANDER I2C 16BIT 24TSSO

The TCA9539A-Q1 is a 24-pin device that provides 16 bits of general purpose parallel input and output (I/O) expansion for the two-line bidirectional I2C bus (or SMBus protocol). The device can operate with a power supply voltage (VCC) range from 1.65V to 5.5V. The device supports 100kHz (I2C Standard mode) and 400kHz (I2C Fast mode) clock frequencies. I/O expanders such as the device 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 device include an interrupt that is generated on the INT pin when an input port changes state. The A0 and A1 hardware selectable address pins allow up to four devices on the same I2C bus. The device can be reset to its default state by cycling the power supply and causing a power-on reset. Also, the device has a hardware RESET pin that can be used to reset the device to its default state. The TCA9539A-Q1 I2C I/O expander is qualified for automotive applications.
