MAX14854GWE+T

Drivers, Receivers, Transceivers Overview

The MAX14854GWE+T is a full-duplex isolated RS-485/RS-422 transceiver providing 2750V RMS galvanic isolation between the UART and cable sides. It supports data rates up to 25Mbps with one driver and one receiver channel. The device features an integrated LDO for cable-side power, ±35kV ESD protection on bus pins, and operates from -40°C to +105°C. Supply voltages range from 1.71V to 5.5V for VDDA and 3.0V to 5.5V for VDDB.

Drivers, Receivers, Transceivers Feature Summary

• Integrated low-dropout regulator provides dedicated cable-side power supply
• High common-mode transient immunity ensures reliable communication across isolation barriers
• True fail-safe circuitry maintains logic-high output during input faults or open circuits

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. Confirm package marking matches the wide-body SOIC-16 specification. Ensure the ordering suffix corresponds to tape-and-reel packaging requirements for automated assembly processes.

Drivers, Receivers, Transceivers Selection Notes

Select this model when high-speed 25Mbps communication is required alongside robust electrical isolation. The integrated LDO simplifies design by eliminating external voltage regulation for the isolated side. Verify that the system ground potential differences remain within the specified isolation limits.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX1485x family of isolated transceivers. It shares the same physical package and pinout as the MAX14852 but offers significantly higher data throughput capabilities. The family addresses applications requiring noise immunity in electrically noisy industrial environments.

Drivers, Receivers, Transceivers Replacement Considerations

MAX14852 serves as a lower-speed alternative within the same package. Verify isolation ratings and data rate requirements before substitution. Other isolated RS-485 devices may require schematic modifications due to differing pin configurations.
