MAX14880AWE+T

Drivers, Receivers, Transceivers Overview

The MAX14880AWE+T is a high-speed isolated CAN transceiver from the Analog Devices / Maxim Integrated MAX14878–MAX14880 family. It integrates galvanic isolation between the controller side and the physical CAN bus, providing up to 5000VRMS (60s) of isolation in a wide-body 16-pin SOIC package. The device supports data rates up to 1Mbps and features an integrated standby input (STB) for low-power operation. It operates with a controller-side supply voltage range of 1.71V to 5.5V and a bus-side supply of 4.5V to 5.5V. Key protection features include ±25V common-mode receiver input range, ±54V fault protection, and ±15kV ESD protection on the bus side.

Drivers, Receivers, Transceivers Feature Summary

• Integrated galvanic isolation breaks ground loops and reduces noise in environments with large ground potential differences.
• Built-in transmitter dominant timeout prevents erroneous controllers from clamping the bus to a dominant level.
• Wide fault protection range simplifies external TVS component selection for surge protection applications.
• Standby mode allows disabling the driver to achieve low-power consumption when not actively transmitting.

• Industrial Controls
• HVAC Systems
• Building Automation
• Switching Gear

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and RoHS compliance status. Ensure that the selected variant matches the required isolation voltage rating and standby functionality for your design. Cross-reference the part number with the latest datasheet revision to confirm availability and any potential pinout or parameter updates before finalizing procurement plans.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring robust galvanic isolation for CAN networks with significant ground potential differences. Consider the 16-pin SOIC package dimensions if board space permits, as it provides wider creepage and clearance distances compared to smaller packages. Evaluate the need for the standby feature; if power saving is critical, ensure the controller can manage the STB pin effectively during idle periods.

Drivers, Receivers, Transceivers Part Context

The MAX14880AWE+T belongs to the MAX14878–MAX14880 family of isolated CAN transceivers. This family includes variants with different isolation ratings (2.75kVRMS, 3.5kVRMS, and 5kVRMS) and package options (8-pin and 16-pin SOIC). The MAX14880 specifically offers the highest isolation rating within the standard lineup and includes the standby feature, distinguishing it from the non-standby MAX14878.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX14878AWE+T is a direct functional substitute within the same family but lacks the standby input pin. Designers must account for the missing STB pin and adjust PCB layout accordingly. Other family members like the MAX14879 offer lower isolation ratings and should only be considered if system requirements allow for reduced withstand voltage capabilities.
