TCA6416PWR TI I2C I/O Expander | 24-TSSOP | 16-bit, 1.65-5.5V

Product Overview

The TCA6416PWR is a 16-bit I/O expander from Texas Instruments designed for I2C-bus applications. It provides general-purpose remote I/O expansion for most microcontroller families via the I2C interface. The device features a 16-bit bidirectional I/O port (P0 and P1) with interrupt output, allowing for easy integration into systems requiring additional I/O lines. Operating from 1.65V to 5.5V, it is ideal for low-voltage applications. The TCA6416PWR comes in a compact 24-TSSOP package, making it suitable for space-constrained designs.
