MAX33071EASA+T

Overview

The MAX33071EASA+T is a half-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc. It operates on a single +3.0V to +5.5V supply voltage and supports data rates up to 2Mbps. The device features ±65V fault protection on driver outputs and receiver inputs, along with a ±40V common-mode range. It incorporates ±40kV Human Body Model ESD protection on the A and B pins. The component includes one driver and one receiver in an 8-pin SO package, operating within a temperature range of -40°C to +125°C.

Feature Summary

• Integrated ±65V fault protection for robust communication in harsh industrial environments
• High ±40V common-mode range exceeding standard RS-485 specifications
• Hot-swap input structure prevents false transitions during power-up or insertion
• True fail-safe receiver guarantees logic-high output when inputs are open or shorted

Applications

• Industrial automation equipment
• Home and building automation systems
• Power supply and UPS units
• Elevator control networks
• Motion controllers

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and RoHS compliance status. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the procurement channel provides valid traceability documents matching the manufacturer's part identification standards.

Selection Notes

Select this component for applications requiring high-speed data transmission up to 2Mbps alongside significant overvoltage tolerance. The wide common-mode range makes it suitable for systems with large ground potential differences. Verify that the 8-pin SO package footprint aligns with the target PCB layout constraints.

Part Context

This device belongs to the MAX33070E/MAX33071E/MAX33074E family of fault-protected transceivers. While sharing identical protection features and pinouts, the MAX33071E specifically targets higher bandwidth requirements compared to the 500kbps MAX33070E. All variants share the same thermal and electrical protection mechanisms.

Replacement Considerations

The MAX33070E and MAX33074E are direct pin-compatible alternatives within the same family. The MAX33070E offers lower data rates, while the MAX33074E supports higher speeds up to 20Mbps. No external circuit changes are required for substitution.
