3 Description

The SN65HVD1050 meets or exceeds the

specifications of the ISO 11898 standard for use in applications employing a Controller Area Network

(CAN).

As a CAN transceiver, this device provides differential

transmit capability to the bus and differential receive

capability to a CAN controller at signaling rates up to

1 megabit per second (Mbps) (1).

The SN65HVD1050 is designed for operation in

especially harsh environments. As a result, the device

features cross-wire, overvoltage and loss of ground

protection from –27 V to 40 V, overtemperature

shutdown, a –12-V to 12-V common-mode range, and

will withstand voltage transients from –200 V to 200 V

according to ISO 7637.
