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. Isolation improves communication by breaking ground loops and reduces noise where there are large differences in ground potential between ports. The MAX14879 provides up to 2750V_RMS (60s) of galvanic isolation, while the MAX14878/MAX14880 provide up to 5000V_RMS (60s) of galvanic isolation in 8-pin and 16-pin SOIC packages.

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.

The MAX14878–MAX14880 transceivers feature integrated protection for robust communication. The receiver input common-mode range is ±25V, exceeding the ISO 11898 specification of -2V to +7V, and are fault tolerant up to ±54V. Driver outputs/receiver inputs are also protected from ±15kV electrostatic discharge (ESD) to GNDB on the bus side, as specified by the Human Body Model (HBM).

Interfacing with CAN protocol controllers is simplified by the wide 1.71V to 5.5V supply voltage range (VDDA) on the controller side of the device. This supply voltage sets the interface logic levels between the transceiver and controller. The supply voltage range for the CAN bus side of the device is 4.5V to 5.5V (VDDB).

The MAX14878–MAX14880 are available in a wide-body 16-pin SOIC package with 8mm of creepage and clearance. The MAX14878 is also available in 8-pin wide-body SOIC packages with 5mm (MAX14878) and 8mm (MAX14878W) creepage. All devices operate over the -40°C to +125°C temperature range.
