Maxim Integrated — MAX14878/79/80: 2.75kV and 5kV Isolated CAN Transceivers

The MAX14878-MAX14880 family of high-speed transceivers improve communication and safety by integrating galvanic isolation between the CAN protocol controller side of the device and the physical wires of the network (CAN) bus. The MAX14879 provides up to 2750VRMS (60s) of galvanic isolation, while the MAX14878/MAX14880 provide up to 5000VRMS (60s) of galvanic isolation. All transceivers operate up to the maximum high-speed CAN data rate of 1Mbps. The MAX14879/MAX14880 feature an integrated standby input (STB) on the isolated side of the transceiver to disable the driver and place the transceiver in a low-power standby mode. The MAX14878 does not include the standby input.
