3 Description

This CAN transceiver meets the ISO1189-2 High

Speed CAN (Controller Area Network) physical layer standard. It is designed for data rates in excess of 2

Mpbs (megabits per second) for CAN FD (CAN with

flexible data rate), greater than 1 Mbps for CAN in

short networks, and enhanced timing margin and

higher data rates in long and highly-loaded networks.

The device provides many protection features to enhance device and CAN-network robustness. The

SN65HVD267 adds additional features, allowing easy

design of redundant and multi-topology networks with

fault indication for higher levels of safety in the CAN

system.
