The part handles the standard 1 Mbps CAN data rate and includes a 100 mV receiver hysteresis for noise rejection on the bus.
The wide range means you can run it in the same enclosure as a hot power supply without derating the bus interface.
The transceiver itself runs on 3.3V, but the CAN bus differential signals are compatible with a 5V CAN bus at the physical layer. The recessive and dominant voltage levels on the bus are defined by the transceiver's driver, not the supply rail of the controller. No level shifter is needed between the 3.3V transceiver and a 5V CAN bus.
