Industrial CAN Transceivers
SN65HVD255/6/7
These CAN transceivers meet the ISO1189-2 High Speed CAN (Controller Area
Network) Physical Layer standard. They are designed for data rates in excess of 1
megabit per second (Mbps) in short networks or CAN FD applications, and enhanced
timing margin and higher data rates in long and highly-loaded networks. These devices
provide many protection features to enhance device and CAN-network robustness. The
SN65HVD257 adds additional features, allowing easy design of redundant and multi-
topology networks with fault indication for higher levels of functional safety in the CAN
system.
