SN65HVD256 CAN Transceiver With Fast Loop Times for Highly Loaded Networks |


CAN Transceiver With Fast Loop Times for Highly Loaded Networks


Recommended alternative parts

  • ISO1050  - The device has SIMILAR FUNCTIONALITY but is not functionally equivalent to the compared device.   Isolated CAN


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.
