High-Speed Fault-Tolerant CAN Transceiver IC for Automotive Low-Speed Networks up to 125 kbps (SOIC-14)

The TJA1055T/1J is a fault-tolerant CAN transceiver designed to interface a CAN protocol controller with the physical bus in automotive and industrial communication systems. Optimised for low-speed CAN networks up to 125 kbps, this IC enables reliable differential data transmission while maintaining robust communication even in the presence of wiring faults or disturbances. It is widely used in in-vehicle networks for body electronics, diagnostics, and comfort systems.

This device enhances system reliability by automatically switching to single-wire operation in case of bus faults, ensuring continued communication under degraded conditions. As an improved version of earlier devices, it offers better electromagnetic compatibility (EMC), reduced emissions, and enhanced protection features. The SOIC-14 package allows easy integration into automotive-grade PCB designs, making it suitable for harsh environments requiring dependable CAN communication.
