More Information

The TCA9539-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 1.65 V to 3.6 V. The device supports 100 kHz (I2C Standard mode) and 400 kHz (I2C Fast mode) clock frequencies. I/O expanders such as the TCA9539-Q1 provide a simple solution when additional I/Os are needed for switches, sensors, push-buttons, LEDs, fans, and other similar devices.
