Semiconductors, the TJA1042T1J is designed to provide a CAN High Speed physical interface for communication controllers in automotive applications. It is a low power transceiver that offers an extended common mode range to facilitate in-vehicle communication in harsh environments. It is suitable for both standard CAN buses and CAN FD buses and provides configurable drivers and receivers for flexible signal performance. With an integrated ESD protection circuit, the TJA1042T1J provides in-circuit protection from voltage transients or electrostatic discharges. This CAN interface IC also has built-in test features such as a loop-back mode for testing and a non-destructive local bus monitoring to provide programmable data and error messages to debugging tools. Additionally, it is designed to minimize electromagnetic radiation with built-in shielding and integrated termination resistors for improved EMC performance.
