Overview
The TJA1040T/N,112 is a high-speed Controller Area Network (CAN) transceiver produced by NXP USA Inc. This component serves as the interface between the CAN protocol controller and the physical bus, primarily designed for high-speed applications up to 1 MBaud, particularly in passenger cars. It is known for its low-current standby mode with remote wake-up capability, making it an excellent choice for nodes that can be in power-down or standby mode in partially powered networks.
