MAX14949EWE+T

Digital Isolators Overview

The MAX14949EWE+T is a half-duplex RS-485/RS-422 transceiver featuring integrated capacitive isolation and an on-board transformer driver. It supports data rates up to 500kbps with 5kVrms isolation voltage. The device operates from a 1.71V to 5.5V supply, includes 30kV ESD protection, and utilizes a 16-pin SOIC-Wide package.

Digital Isolators Feature Summary

• Integrated transformer driver for isolated power transfer
• Capacitive coupling technology for signal isolation
• High electromagnetic interference immunity

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation
• Building automation networks
• Process control instrumentation

Digital Isolators Procurement Notes

Verify the specific suffix 'EWE+T' against official Analog Devices documentation to confirm the tape-and-reel packaging configuration and lead-free status. Ensure the design accounts for the external transformer requirements specified in the datasheet for proper isolation barrier implementation.

Digital Isolators Selection Notes

Select this component when both high-voltage isolation and isolated power delivery are required within a single interface solution. It is suitable for designs needing robust noise immunity in electrically noisy environments where traditional optocoupler or digital isolator plus separate power supply approaches are less efficient.

Digital Isolators Part Context

This part belongs to the MAX149xx family of isolated RS-485/RS-422 transceivers. Unlike standard isolators that only pass data, this series integrates the power conversion stage, simplifying the bill of materials by eliminating the need for a separate isolated DC-DC converter for the remote side.

Digital Isolators Replacement Considerations

MAX14948EWE+T offers similar functionality but may differ in specific isolation ratings or pinout configurations. Verify electrical parameters and mechanical dimensions before substitution.
