MCP2551-I/P

Product Summary

The MCP2551-I/P is a high-speed CAN, fault-tolerant transceiver that serves as the interface between a CAN protocol controller and the physical bus. The MCP2551-I/P provides differential transmit and receive capability for the CAN protocol controller, and is fully compatible with the ISO-11898 standard, including 24V requirements. It will operate at speeds of up to 1 Mb/s. Typically, each node in a 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 (differential output). The MCP2551-I/P also provides a buffer between the CAN controller and the high-voltage spikes that can be generated on the CAN bus by outside sources (EMI, ESD, electrical transients, etc.).
