MAX14856GWE+

Drivers, Receivers, Transceivers Overview

The MAX14856GWE+ 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 500kbps with a maximum supply voltage of 5.5V on both logic (VDDA) and cable (VDDB) sides. The device features ±35kV ESD protection on driver outputs and receiver inputs, an integrated LDO for cable-side power, and operates within a temperature range of -40°C to +105°C in a 16-pin wide SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated low-dropout regulator simplifies cable-side power management
• High common-mode transient immunity ensures robust communication across isolation barriers
• True fail-safe circuitry maintains logic-high receiver 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 component authenticity through authorized Analog Devices distributors. Confirm RoHS compliance status via official documentation. Ensure ordering suffixes match required packaging formats. Validate datasheet revision against current manufacturing specifications before integration into production designs.

Drivers, Receivers, Transceivers Selection Notes

Select this model for applications requiring high-speed full-duplex communication over isolated RS-485 networks. The integrated LDO reduces external component count compared to non-LDO variants. Verify that the 500kbps data rate meets system requirements, as higher speeds require the MAX14858 variant.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX1485x family of isolated transceivers. It shares architectural similarities with the MAX14852 and MAX14855 but offers distinct isolation voltage ratings and data rate capabilities. The GWE+ suffix indicates a lead-free, halogen-free wide SOIC package compliant with specific environmental standards.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX14858GWE+ serves as a direct functional substitute offering increased data rates up to 25Mbps while maintaining identical pinouts and isolation characteristics.
