MAX14878MAX14880 2.75kV, 3.5kV, and 5kV Isolated CAN Transceivers General Description Benefits and Features The MAX14878MAX14880 family of high-speed trans- Integrated Protection for Robust Communication ceivers improve communication and safety by integrating 2.75kV , 3.5kV , or 5kV Withstand RMS RMS RMS galvanic isolation between the CAN protocol controller Isolation Voltage for 60s (Galvanic Isolation) side of the device and the physical wires of the network 25V Receiver Input Common-Mode Range (CAN) bus. Isolation improves communication by breaking 54V Fault Protection on Receiver Inputs ground loops and reduces noise where there are large High-Performance Transceiver Enables Flexible differences in ground potential between ports. The Designs MAX14879 provides up to 2750V (60s) of galvanic RMS Wide 1.71V to 5.5V Supply for the CAN Controller isolation, while the MAX14878/MAX14880 provide up to Interface 5000V (60s) of galvanic isolation in 8-pin and 16-pin RMS Available 16-pin and 8-pin SOIC Package Pin SOIC packages. Configurations All transceivers operate up to the maximum high-speed Data Rates up to 1Mbps (Max) CAN data rate of 1Mbps.

The MAX14878 does UL According to UL1577 (Basic Insulation) (16-Pin not include the standby input. Package Devices Only) The MAX14878MAX14880 transceivers feature integrat- ed protection for robust communication. The receiver input Ordering Information appears at end of data sheet. 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 (V ) on DDA the controller side of the device. This supply voltage sets the interface logic levels between the transceiver and con- troller. The supply voltage range for the CAN bus side of the device is 4.5V to 5.5V (V ). DDB The MAX14878MAX14880 are available in a wide-body 16-pin SOIC package with 8mm of creepage and clear- ance. The MAX14878 is also available in 8-pin wide-body SOIC packages with 5mm (MAX14878) and 8mm (MAX14878W) creepage. All devices operate over the -40C to +125C temperature range.
