Product Introduction

Overview

The PCA6408APW,118, produced by NXP USA Inc., is an 8-bit general purpose I/O expander designed to provide remote I/O expansion for most microcontroller families via the I²C-bus interface. This device is particularly useful in scenarios where additional I/Os are required without increasing the complexity of interconnections. It is suitable for various applications, including battery-powered mobile devices, sensor interfaces, push buttons, and keypads.
