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 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 SN65HVD257 device adds additional features, allowing for easy design of redundant and multitopology networks with fault indication for higher levels of functional safety in the CAN system.
