Texas Instruments SN65HVD267 CAN Transceiver

Texas Instruments SN65HVD267 CAN Transceiver meets the ISO1189-2 High Speed CAN (Controller Area Network) physical layer standard. This device is designed for data rates in excess of 2Mpbs for CAN FD (CAN with flexible data rate) and greater than 1Mbps for CAN in short networks. The transceiver allows for enhanced timing margin and higher data rates in long and highly-loaded networks. The Texas Instruments SN65HVD267 provides many protection features to enhance device and CAN-network robustness. The device adds additional features, allowing easy design of redundant and multi-topology networks with fault indication for higher levels of safety in the CAN system.
