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.
