onsemi NCV7351D1ER2G, CAN Transceiver 1Mbps ISO 11898-2, 8-Pin SOIC

A range of Controller Area Network (CAN) protocol controllers and transceivers from ON Semiconductor. The transceivers provide differential transmit capability to the bus and differential receive capability to the CAN controller.

CAN Bus (Controller Area Network) Communication

Controller Area Network (CAN or CAN-bus) is a computer network protocol and bus standard designed to allow microcontrollers and devices to communicate with each other without a host computer. It was designed specifically for automotive applications but is now also used in other areas.
CAN transceivers allow protocol layer CAN controllers to access the physical layer bus.
