Overview
The TJA1054T/S900,518 is a fault-tolerant CAN (Controller Area Network) transceiver produced by NXP USA Inc. This device serves as the interface between the protocol controller and the physical bus wires in a CAN network. It is primarily designed for low-speed applications up to 125 kBd, particularly in passenger cars. The TJA1054T/S900,518 offers differential receive and transmit capabilities and can switch to single-wire transmitter and/or receiver in error conditions, ensuring robust and reliable communication even under fault scenarios.
