MAX14857GWE+

Drivers, Receivers, Transceivers Overview

The MAX14857GWE+ is a full-duplex isolated RS-485/RS-422 transceiver in a 16-pin Wide SOIC package. It provides 5000V RMS galvanic isolation and supports data rates up to 500kbps. The device features an integrated 450kHz transformer driver and an LDO for cable-side power transfer, eliminating the need for external isolated supplies. It operates on 3.0V to 5.5V logic and field-side supplies, with ±35kV ESD protection on bus pins and a -40°C to +105°C operating range.

Drivers, Receivers, Transceivers Feature Summary

• Integrated transformer driver and LDO simplify isolated power architecture
• High common-mode transient immunity ensures robust signal integrity
• True fail-safe receiver guarantees high output during open or shorted conditions

• Industrial Automation Equipment
• Programmable Logic Controllers
• HVAC Systems
• Power Meters

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'GWE+' against the manufacturer's official documentation to confirm the wide-body SOIC-16 package and lead-free status. Ensure the component matches the exact datasheet revision required for your design specifications before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high-speed full-duplex communication across significant ground potential differences. The integrated power transfer capabilities reduce bill-of-materials complexity compared to discrete isolation solutions. Verify that the external transformer selection meets the minimum ET product requirements for the intended supply voltage.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX1485x family of isolated transceivers designed for harsh industrial environments. It shares architectural similarities with the MAX14859 but is optimized for lower data rate applications up to 500kbps. The family utilizes advanced capacitive isolation technology to maintain signal integrity while providing high-voltage barrier protection.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX14859GWE+ serves as a functional substitute within the same series, offering identical pinouts and isolation features but supporting higher data rates up to 25Mbps. Designers must verify that the system timing constraints accommodate the faster switching speeds if upgrading from the MAX14857.
