TCA6416ARTWR TI I2C I/O Expander | 24-WQFN (4x4) | 16-bit, 1.65-5.5V

Product Overview

The TCA6416ARTWR is a 16-bit I2C-bus and SMBus I/O expander from Texas Instruments. It provides general-purpose remote I/O expansion for most microcontroller families via the I2C interface (serial clock (SCL) and serial data (SDA)). The device features a 16-bit bidirectional I/O port (P00-P07, P10-P17) including a latch with high-current drive capability for directly driving LEDs. The TCA6416ARTWR operates from a supply voltage range of 1.65 V to 5.5 V and is available in a compact 24-pin WQFN (4x4 mm) package.
