This 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 2 Mbps (megabits per second). Devices with part numbers that include the "G" suffix are designed for data rates up to 5 Mbps, 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.

Terminal 5 function is device dependent; NC on devices without the "V" suffix, and VIO for I/O level shifting for devices with the "V" suffix.
RXD logic output is driven to VCC on devices without the "V" suffix, and VIO for devices with the "V" suffix.
