The MCP2551 CAN transceiver from Microchip Technology Inc. is suitable for 12V and 24V systems, has a transient voltage tolerance of 1250V, and withstands 140V shortcircuit voltage, making them suitable for automotive and industrial applications.

The device is further protected from excessive current loading by automatic thermal shutdown circuitry that disables the output drivers when the junction temperature exceeds a nominal limit of 1650C.

Available in 8-pin PDIP and SOIC packages, the device serves as the interface between a CAN-protocol controller and a system's physical bus. It provides differential transmit and receive capability, enabling nodes to be connected to the same network.

The transceiver complies with the ISO11898 standard, providing data rates of up to 1Mbps for a network of nodes for road vehicles using CAN.

The MCP2551 features externally-controlled output slope capability to reduce RFI emissions and costs by using unshielded wires.

It is priced at $1.29 each in 1,000-unit quantities.
