TCAL6416RTWR TI I2C I/O Expander | 24-WQFN (4x4) | 16-bit, 1.65-5.5V

Product Overview

The TCAL6416RTWR from Texas Instruments is a 16-bit I2C-bus and SMBus I/O expander with interrupt output, reset, and configuration registers. It provides general-purpose remote I/O expansion for most microcontroller families via the I2C interface (serial clock and serial data). The device features a wide operating voltage range of 1.65 V to 5.5 V, making it suitable for various low-voltage applications. The 24-pin WQFN package (4x4 mm) offers a compact solution for space-constrained designs.
