DESCRIPTION/

ORDERING INFORMATION

The SN65HVD1050 meets or exceeds the

specifications of the ISO 11898 standard for use in

applications employing a controller area network

(CAN). The device is also qualified for use in

automotive applications in accordance with

AEC-Q100.(2)

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)(3).

Designed for operation in especially harsh

environments, the SN65HVD1050 features

cross-wire, overvoltage, and loss of ground protection from –27 V to 40 V, overtemperature protection, a

–12-V to 12-V common-mode range, and withstands

voltage transients from –200 V to 200 V, according to

ISO 7637.

Pin 8 provides for two different modes of operation:

high-speed or silent mode. The high-speed mode of

operation is selected by connecting S (pin 8) to

ground.
