TCA9539QPWRQ1 TI I2C GPIO Expander | 24-TSSOP | 16-bit, 1.65-5.5V

Product Overview

The TCA9539QPWRQ1 is a 16-bit I2C-bus and SMBus I/O expander from Texas Instruments, designed for automotive applications. It provides 16 general-purpose I/O pins (GPIOs) that can be configured as inputs or outputs via the I2C interface. The device operates from 1.65V to 5.5V, making it suitable for low-voltage and mixed-voltage systems. It features interrupt output, open-drain active-low interrupt, and three hardware address pins allowing up to eight devices on the same bus. The TCA9539QPWRQ1 is qualified to AEC-Q100 for automotive applications.
