MAX14858GWE+T

Drivers, Receivers, Transceivers Overview

The MAX14858GWE+T is a full-duplex isolated RS-485/RS-422 transceiver providing 5000V RMS galvanic isolation between the UART and cable sides. It supports data rates up to 25Mbps with ±35kV ESD protection on driver outputs and receiver inputs. The device features an integrated LDO for cable-side power, true fail-safe circuitry, and thermal shutdown. Operating over -40°C to +105°C, it utilizes a wide-body 16-pin SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated low-dropout regulator supplies cable-side power
• High common-mode transient immunity ensures robust communication
• True fail-safe receiver output prevents undefined states during bus faults

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability requirements against current project specifications before finalizing acquisition.

Drivers, Receivers, Transceivers Selection Notes

Select this model when high-speed 25Mbps communication across significant ground potential differences is required. Ensure design accommodates the 5000V RMS isolation barrier and verify that the integrated LDO meets the cable-side power budget without external regulation.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX1485x family of isolated transceivers. It shares architectural similarities with the MAX14856 but offers higher throughput capabilities. The series addresses industrial needs for noise-immune serial communication in electrically noisy environments.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX14856EWE+T serves as a functional substitute within the same family, offering identical isolation and pinout but limited to 500kbps data rates. Verify speed requirements match application needs before swapping.
