The Microchip MCP2551 is a high-speed CAN Transceiver that can operate at speeds of up to 1 Mbps. Serving as an interface between a CAN Controller and the physical bus, the MCP2551 provides differential transmit and receive capability and is fully compatible with ISO 11898. The MCP2551 is suitable for both 12 V and 24 V systems.

Supports 1 Mbps operation
Slope control input
Implements ISO 11898 physical layer requirements
Suitable for 12 V and 24 V systems
Externally controlled slope for reduced RFI emissions
Permanent dominant detect
Low-current standby operation
High noise immunity due to differential bus implementation

The Microchip MCP2551 high speed CAN transceiver provides differential transmit and receive capability for the CAN protocol controller and is fully compatible with the ISO-11898 standard including 24V requirements. Each node in CAN system must have a device to convert the digital signals generated by a CAN controller to signals suitable for transmission over the bus cabling. It also provides a buffer between the CAN controller and the high-voltage spikes that can be generated on the CAN bus by outside sources.
