MAX14852GWE+T

Drivers, Receivers, Transceivers Overview

The MAX14852GWE+T is a full-duplex isolated RS-485/RS-422 transceiver in a 16-pin wide SOIC package. It provides 2750V RMS galvanic isolation between the UART and cable sides, supporting data rates up to 500kbps. The device features an integrated LDO for cable-side power, ±35kV ESD protection on bus pins, and true fail-safe circuitry. Supply voltage ranges from 1.71V to 5.5V on the logic side and 3.0V to 5.5V on the cable side. Operating temperature spans -40°C to +105°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated low-dropout regulator simplifies cable-side power supply design
• High-voltage capacitive isolation breaks ground loops and reduces noise
• Robust protection against electrostatic discharge and electrical surges

Drivers, Receivers, Transceivers Applications

• Industrial automation equipment
• Programmable logic controllers
• HVAC systems
• Power meters

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm that the component matches the Analog Devices / Maxim Integrated manufacturing origin. Ensure the part number corresponds to the 500kbps MAX14852 variant rather than the 25Mbps MAX14854 version.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high common-mode transient immunity and robust communication across significant ground potential differences. The integrated LDO reduces external component count. Verify that the required data rate does not exceed 500kbps, as higher speeds require the MAX14854 variant.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX14852/MAX14854 family of isolated transceivers. It shares the same pinout and isolation architecture with the MAX14854, differing primarily in maximum data rate capabilities. Both variants utilize the wide-body 16-pin SOIC package for enhanced creepage and clearance distances.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX14854 serves as a functional replacement if higher data rates are acceptable. Other isolated RS-485 transceivers may be considered but will likely require external LDOs and different pin configurations.
