CAN Transceiver with Fast Loop Times for Highly Loaded Networks and Features for Functional Safety - SN65HVD257

SN65HVD257 (ACTIVE)

CAN Transceiver with Fast Loop Times for Highly Loaded Networks and Features for Functional Safety

 

Recommended alternative parts

  • ISO1050  - The device has SIMILAR FUNCTIONALITY but is not functionally equivalent to the compared device.   Combines Isolation and CAN, but has different feature set than the SN65HVD257

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 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.
