Features, Applications

The MAX14878MAX14880 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 (60s) of galvanic isolation, while the MAX14878/MAX14880 provide (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. The MAX14878MAX14880 transceivers feature integrated protection for robust communication. The receiver input common-mode range is 25V, exceeding the ISO 11898 specification to +7V, and are fault tolerant 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 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 to 5.5V (VDDB). The MAX14878MAX14880 are available in a wide-body 16-pin SOIC package with 8mm of creepage and clearance. These devices operate over the to +125C temperature range.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
