Overview
The TJA1054T/S900,512 is a fault-tolerant CAN (Controller Area Network) transceiver produced by NXP USA Inc. This device serves as the interface between the CAN protocol controller and the physical bus wires in a CAN network. It is primarily designed for low-speed applications, up to 125 kBd, and is particularly suited for use in passenger cars. The TJA1054T/S900,512 offers differential receive and transmit capabilities and can switch to single-wire transmitter and/or receiver in error conditions, enhancing its fault tolerance and reliability.
