TCA6424ARGJR TI I2C I/O Expander | 32-UQFN (5x5) | 24-bit, 1.65-5.5V

Product Overview

The TCA6424ARGJR from Texas Instruments is a 24-bit I2C-bus I/O expander designed for 1.65-V to 5.5-V VCC operation. 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 24 configurable input/output pins, three hardware address pins allowing up to eight devices on the same bus, and an active-low reset input. The TCA6424A is available in a compact 32-pin UQFN (5x5 mm) package, making it ideal for space-constrained applications.
