TCA6424RGJR TI I2C I/O Expander | 32-UQFN (5x5) | 24-bit, 1.65-5.5V

Product Overview

The TCA6424RGJR from Texas Instruments is a 24-bit I2C-bus and SMBus I/O expander designed for 1.65-V to 5.5-V VCC operation. It provides 24 general-purpose I/O (GPIO) pins in a compact 32-pin UQFN (5x5 mm) package. The device features interrupt output, programmable polarity, and three hardware address pins allowing up to eight devices on the same bus. It is ideal for applications requiring additional I/O lines in space-constrained designs.
