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 component 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 device is available in a SOIC-14 package and operates within a temperature range of -40°C to +85°C.
