MAX14871EUE+T

Overview

The MAX14871EUE+T is a single-channel, half-duplex RS-485/RS-422 transceiver featuring integrated digital isolation and an isolated DC-DC power supply. It operates on a single 3.3V or 5V supply with data rates up to 10 Mbps. The device provides 5 kV RMS isolation capability and includes thermal shutdown and short-circuit protection.

Feature Summary

• Integrates iCoupler signal isolation and isolated power generation within a single package
• Supports both half-duplex RS-485 and full-duplex RS-422 communication protocols
• Includes diagnostic fault reporting and ready status indicators for system monitoring

Applications

• Industrial automation control systems requiring galvanic isolation
• Building automation networks utilizing RS-485 bus topologies
• Medical equipment interfaces demanding high isolation safety standards

Procurement Notes

Verify the specific suffix EUE against the manufacturer's current datasheet to confirm pinout and packaging details. Confirm RoHS compliance status as indicated in the official documentation before finalizing procurement specifications.

Selection Notes

Select this component when design constraints require minimizing external isolation components. It is suitable for applications needing robust noise immunity and simplified PCB layout compared to discrete optocoupler solutions.

Part Context

This part belongs to the MAX1487x family of isolated transceivers. It replaces traditional multi-component isolation designs by combining the transceiver, isolator, and power converter into one compact QFN package.

Replacement Considerations

Check for direct pin-compatible upgrades within the MAX1487x series. Verify that alternative isolated transceivers meet the same 5kV RMS isolation voltage requirements and data rate specifications.
