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.

Functional Block Diagram

Terminal 5 function is device dependent; NC on SN65HVD265, V_RXD for RXD output level-shifting device on SN65HVD266, and FAULT Output on SN65HVD267

RXD logic output is driven to 5V V_CC on 5V-only supply devices (SN65HVD265, SN65HVD267) and driven to V_RXD on output level-shifting device (SN65HVD266).

RXD (Receiver) Dominant State Time Out is a device dependent option available only on SN65HVD267.
