Maxim Integrated MAX14878 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 bus

Maxim MAX14878 product picture

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 2750VRMS (60s) of galvanic isolation, while the MAX14878/MAX14880 provide up to 5000VRMS (60s) of galvanic isolation.
