MAX14852GWE+

Drivers, Receivers, Transceivers Overview

The MAX14852GWE+ is a full-duplex isolated RS-485/RS-422 transceiver in a 16-pin wide SOIC package. It provides 2750V RMS galvanic isolation between the UART and cable sides, supporting data rates up to 500kbps. The device features an integrated LDO for cable-side power, ±35kV ESD protection on driver outputs and receiver inputs, and operates over a -40°C to +105°C temperature range. Supply voltages are 1.71V to 5.5V for VDDA and 3.0V to 5.5V for VDDB.

Drivers, Receivers, Transceivers Feature Summary

• Integrated low-dropout regulator simplifies cable-side power supply design
• High common-mode transient immunity ensures reliable communication across isolation barriers
• True fail-safe circuitry maintains logic-high output during open or shorted bus conditions

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the component against official Analog Devices documentation to confirm pinout compatibility and electrical specifications. Ensure that the wide-body 16-pin SOIC package dimensions match the target PCB footprint. Confirm that the operating voltage ranges align with the system's power architecture before integration.

Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed full-duplex communication requires robust galvanic isolation. The integrated LDO reduces external component count compared to non-integrated solutions. Verify that the 500kbps data rate meets application requirements, as higher speeds require the MAX14854 variant.

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 other Maxim Integrated interface ICs but offers specific isolation ratings and ESD protection levels tailored for RS-485 networks.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX14854EWE+ serves as a functional substitute within the same series, offering identical isolation and pinout but supporting higher data rates up to 25Mbps. Verify thermal performance and current consumption differences when substituting.
