Product Introduction

Overview

The TJA1051T/E/1J is a high-speed CAN transceiver produced by NXP USA Inc., designed to provide an interface between a Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus. This transceiver is part of the third generation of high-speed CAN transceivers from NXP Semiconductors, offering significant improvements over earlier models like the TJA1050. It is specifically tailored for high-speed CAN applications in the automotive industry, ensuring reliable communication at data rates up to 5 Mbit/s in the CAN FD fast phase, as defined by ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5 standards.
