High-Speed CAN FD Transceiver with Standby Mode (5Mbps, SOIC-8)
The TJA1042 is a high-speed CAN transceiver that provides an interface between a Controller Area Network (CAN) protocol controller and the physical dual-wire CAN bus. Designed for automotive and industrial applications, it offers CAN FD (Flexible Data-rate) performance up to 5 Mbps, standby mode with wake-up capability, and low ElectroMagnetic Emission (EME). It is a vital component in vehicle body control modules, EPS, and industrial CAN nodes where long-term component availability is critical.
