Product Introduction

Overview

The TJA1055T/3/2Z is an enhanced fault-tolerant CAN (Controller Area Network) transceiver manufactured by NXP USA Inc. This device is primarily designed for low-speed CAN applications up to 125 kBd, particularly in passenger cars. It serves as the interface between the protocol controller and the physical bus wires, providing differential receive and transmit capabilities. The TJA1055T/3/2Z also features automatic switching to single-wire transmitter and/or receiver in error conditions, ensuring robust and reliable communication in various operational scenarios.
