The SN65HVD251 is intended for use in applications employing the Controller Area Network (CAN) serial communication physical layer in accordance with the ISO 11898 Standard. The SN65HVD251 provides differential transmit capability to the bus and differential receive capability to a CAN controller at speeds up to 1 megabit per second (Mbps).

Designed for operation in harsh environments, the device features crosswire, overvoltage, and loss of ground protection to ±36 V. Also featured are overtemperature protection as well as -7-V to 12-V common-mode range, and tolerance to transients of ±200 V. The transceiver interfaces the single-ended CAN controller with the differential CAN bus found in industrial, building automation, and automotive applications.
