The TJA1050 is the interface between the CAN protocol controller and the physical bus. The device provides differential transmit capability to the bus and differential receive capability to the CAN controller. The TJA1050 is the successor to the PCA82C250 high-speed CAN transceiver.The most important improvements are:1.Much lower Electromagnetic Emission (EME) due to the optimal matching of the CANH and CANL output signals2.Improved behavior in case of an unpowered node.
