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.

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.
