The TJA1055T/C,512 is a CAN Transceiver, interface between the protocol controller and the physical bus wires in a controller area network (CAN). It is primarily intended for low-speed applications up to 125kBd in passenger cars. The device provides differential receive and transmit capability but will switch to single-wire transmitter and/or receiver in error conditions. The TJA1055T/C,512 is the enhanced version of the TJA1054 and TJA1054A. TJA1055T/C,512 has the same functionality but in addition offering a number of improvements.
