　　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 of devices comes with silent mode which is also commonly referred to as listen-only mode. AddiTIonally， all devices include many protecTIon features to enhance device and network robustness.
