MAX14938GWE+T

Digital Isolators Overview

The MAX14938GWE+T is a half-duplex RS-485 transceiver featuring integrated digital isolation. It supports data rates up to 20Mbps and provides 2.75kVRMS isolation voltage. The device includes 35kV ESD protection on the bus pins and operates within a supply voltage range of 1.71V to 5.5V. It utilizes capacitive coupling technology for signal transmission across the isolation barrier.

Digital Isolators Feature Summary

• Integrates RS-485 transceiver functionality with high-voltage digital isolation in a single package
• Provides robust 35kV electrostatic discharge protection directly on the isolated bus interface
• Utilizes capacitive coupling technology to ensure reliable signal transmission across the isolation barrier

Digital Isolators Applications

• PROFIBUS communication networks requiring galvanic isolation
• Industrial automation systems utilizing RS-485 interfaces
• Equipment needing high common-mode transient immunity in noisy environments

Digital Isolators Procurement Notes

Verify the specific suffix 'GWE+T' against official Analog Devices documentation to confirm pinout, thermal characteristics, and RoHS compliance status. Confirm availability through authorized distributors as supply levels may vary. Ensure the selected component matches the required isolation voltage ratings for your specific safety certification needs.

Digital Isolators Selection Notes

Select this component when designing systems that require both RS-485 connectivity and galvanic isolation without separate discrete components. Consider the 20Mbps data rate capability and the 2.75kVRMS isolation rating relative to system noise immunity requirements. Evaluate the SOIC-Wide-16 package constraints against PCB layout space limitations.

Digital Isolators Part Context

This part belongs to the Maxim Integrated family of isolated interface devices, now under Analog Devices. It combines standard RS-485 driver and receiver circuits with a capacitive digital isolator. This integration simplifies design by reducing component count compared to using separate transceivers and isolators.

Digital Isolators Replacement Considerations

Consult official substitution guides for compatible parts within the MAX149xx series. Verify electrical parameters such as isolation voltage and data rate before swapping.
