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)

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.
