LM8327JGR8X/NOPB TI I/O Expander | 36-CSBGA (3.5X3.5) | 1.8V-5.5V, 24 GPIO

Product Overview

The LM8327JGR8X/NOPB is a low-voltage, 24-pin I/O expander from Texas Instruments designed for I²C-bus/SMBus interface. It provides general-purpose remote I/O expansion for most microcontroller families via a two-wire bidirectional serial bus. The device operates from a supply voltage range of 1.8V to 5.5V, making it suitable for a wide variety of applications. It features 24 configurable GPIO pins, each with internal pull-up resistors, and supports interrupt output for event-driven communication. The compact 36-CSBGA (3.5x3.5mm) package enables space-constrained designs.
