The MCP2542FD 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).

Supports CAN 2.0 and CAN with Flexible Data Rate CAN FD) Physical Layer Transceiver Requirements
Optimized for CAN FD at 2, 5 and 8 Mbps Operation
Maximum propagation delay: 120 ns
Loop delay symmetry: ±10% (2 Mbps)
Wake-up on CAN activity, 3.6 μs filter time
Very Low Standby Current (4 μA, typical)
VIO Supply Pin to Interface Directly to CAN Controllers and Microcontrollers with 1.8V to 5V I/O
CAN Bus Pins are Disconnected when Device is Unpowered
An unpowered node or brown-out event will not load the CAN bus
Device is unpowered if VDD or VIO drop below its POR level
Detection of
