Texas Instruments' CAN transceiver family meets the ISO11898-2 (2016) High Speed CAN (Controller Area Network) physical layer standard. All devices are designed for use in CAN FD networks up to 2Mbps. Devices with part numbers that include the 'G' suffix are designed for data rates up to 5Mbps, and versions with the 'V' have a secondary power supply input for I/O level shifting the input pin thresholds and RXD output level.

This family has a low power standby mode with remote wake request feature. Additionally, all devices include many protection features to enhance device and network robustness.
