Overview
The TJA1055T/3/C,518 is a part of the TJA1055 series, an enhanced 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, particularly in passenger cars. The TJA1055T/3/C,518 offers robust features such as differential receive and transmit capability, automatic switching to single-wire mode in case of bus failures, and high electromagnetic immunity and low electromagnetic emission.
