ADIMAX14853GWE+T
Overview
The MAX14853GWE+T is a robust, isolated full-duplex RS-422/RS-485 transceiver designed to provide high-level galvanic isolation between the cable side and the logic side of the interface. It supports data rates up to 500kbps and integrates a transformer driver for power isolation, significantly reducing board space and complexity in harsh industrial environments. The device operates from a 3V to 5.5V supply and is rated for a wide temperature range of -40degC to 105degC.
Why Choose This Part
The integrated 2750VRMS galvanic isolation eliminates the need for external optocouplers, simplifying the design of safety-critical systems. Its full-duplex capability allows for simultaneous bidirectional communication, while the wide 3V to 5.5V operating range ensures compatibility with both legacy 5V and modern 3.3V logic controllers.
Applications
Key Specifications
Getting Started
To evaluate this transceiver, use the MAX14853EVKIT evaluation kit, which provides a proven PCB layout for testing the isolation and data rate performance. Ensure a suitable transformer is selected for the integrated transformer driver to provide the isolated power rail for the secondary side. When routing the 16-SOIC package, maintain the required creepage and clearance distances to meet your specific safety isolation standards.
