Product Introduction

Overview

The TJA1124AHG/0Z, produced by NXP USA Inc., is a quad Local Interconnect Network (LIN) commander channel device. It serves as the interface between a LIN commander protocol controller and the physical bus in a LIN network. Each of its four channels incorporates a LIN transceiver and LIN commander termination, aligning with the LIN physical layer of the Open System Interconnect (OSI) model. This device is specifically designed for automotive LIN commander applications, supporting multiple LIN commander channels and ensuring excellent ElectroMagnetic Compatibility (EMC) performance.
