Overview

The TJA1042T/3/1J is a high-speed CAN transceiver that provides the physical layer interface between a CAN protocol controller and the physical two-wire CAN bus. This specific variant features a Vio pin for direct interfacing with microcontrollers operating at 3.3V or 5V and is AEC-Q100 qualified for automotive environments.

Why Choose This Part

This transceiver offers very low standby current of 5uA and robust electromagnetic compatibility (EMC) performance. It includes critical safety features such as thermal protection, undervoltage detection, and high-voltage bus protection to ensure system reliability under fault conditions.

Applications

Automotive Body Control
Ideal for electronic control units (ECUs) requiring high-speed communication within vehicle body networks.
Industrial Networking
Reliable CAN communication for industrial automation systems and factory floor sensor networks.
Gateway Modules
Used in gateway systems that bridge different CAN bus segments with varying voltage levels.

Getting Started

To implement this device, connect the TXD and RXD pins to your CAN controller and provide 5V to Vcc. Use the Vio pin to match your microcontroller logic levels (2.8V to 5V), and ensure proper 120-ohm termination is present at the ends of the CAN bus network.
