TI TCA9539QPWRQ1

16I²C，SMBusPOR1.65V ~ 3.6V-40°C ~ 125°C

Overview

The TCA9539-Q1 is a 24-pin device that provides 16 bits of generalpurpose parallel input and output (I/O) expansion for the two-line bidirectionalI2C bus (or SMBus protocol). The device can operate with a power supplyvoltage (VCC) range from 1.65 V to 3.6 V. The device supports 100-kHz(I2C Standard mode) and 400-kHz (I2C Fastmode) clock frequencies. I/O expanders such as the TCA9539-Q1 provide a simple solution whenadditional I/Os are needed for switches, sensors, push-buttons, LEDs, fans, and other similardevices.
