MAX14853GWE+

Drivers, Receivers, Transceivers Overview

The MAX14853GWE+ is a full-duplex isolated RS-485/RS-422 transceiver providing 2750V RMS galvanic isolation between the UART-side and cable-side. It supports data rates up to 500kbps with one driver and one receiver channel. The device features an integrated 450kHz transformer driver for power transfer across the isolation barrier and an internal LDO outputting 3.3V (typ) at VDDB. Driver outputs and receiver inputs offer ±35kV ESD protection (HBM). Operating supply voltage ranges from 3.0V to 5.5V on both sides, with an operating temperature range of -40°C to +105°C in a 16-pin Wide SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated transformer driver and LDO simplify isolated power architecture
• High-performance transceiver compliant with RS-485 standards
• Robust communication ensured by ±35kV ESD protection and thermal shutdown

Drivers, Receivers, Transceivers Applications

Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for pending safety regulatory approvals such as UL, cUL, and VDE before finalizing procurement specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this model when high-speed isolation is not required but robust noise immunity and simplified power design are priorities. Ensure external center-tapped transformers meet the minimum ET product requirement to prevent saturation during operation.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX14853/MAX14855 series of isolated RS-485/RS-422 transceivers. While the MAX14855 variant supports higher speeds up to 25Mbps, the MAX14853 is optimized for applications requiring reliable communication at lower data rates with integrated isolation capabilities.

Drivers, Receivers, Transceivers Replacement Considerations

MAX14855GWE+ offers identical pinout and integration but supports 25Mbps data rates.
