The MCP2542WFD/4WFD CAN transceiver is designed for high-speed CAN FD applications up to 8Mbps communication speed. The maximum propagation delay was improved to support longer bus length.The device meets the automotive requirements for CAN FD bit rates exceeding 2 Mbps, low quiescent current,
electromagnetic compatibility (EMC) and electrostatic discharge (ESD).
