TCA9554DWR TI I2C I/O Expander | 16-SOIC | 8-bit, 2.3V-5.5V

Product Overview

The TCA9554DWR from Texas Instruments is a 16-pin I2C-bus I/O expander providing 8-bit general-purpose parallel I/O expansion for microcontrollers. It operates from 2.3V to 5.5V and supports up to 400 kHz I2C clock frequency. The device features three hardware address pins allowing up to eight devices on the same bus, and includes an interrupt output for pin-change detection. Housed in a 16-SOIC package, it is ideal for applications requiring additional I/O lines.
