MAX3071EESA+

Overview

The MAX3071EESA+ is a full-duplex RS-485 transceiver operating from a single 3.3V supply. It features one driver and one receiver with fail-safe circuitry that guarantees a logic-high output when inputs are open or shorted. The device includes hot-swap capability on the DE and RE pins to prevent false transitions during power-up or insertion. It provides ±15kV Human Body Model ESD protection on I/O pins and supports data rates up to 250kbps with enhanced slew-rate limiting.

Feature Summary

• Full-duplex communication architecture with integrated fail-safe receiver circuitry
• Hot-swap input structure on enable pins to eliminate bus contention during insertion
• ±15kV Human Body Model electrostatic discharge protection on all I/O pins

Applications

• Industrial control systems
• Telecommunications equipment
• Security systems
• Lighting systems
• Instrumentation

Procurement Notes

Verify the specific suffix against official documentation, as ordering codes may indicate variations in temperature range or packaging. Confirm availability status directly with authorized distributors, as lead times and stock levels fluctuate. Ensure the component meets required environmental standards for the intended deployment environment before finalizing procurement.

Selection Notes

Select this model for applications requiring full-duplex RS-485 communication at speeds up to 250kbps. It is suitable for environments where hot-swap functionality and robust ESD protection are critical. Note that this specific variant does not support the low-current shutdown mode found in other members of the MAX3070E family.

Part Context

This component belongs to the MAX3070E–MAX3079E series of 3.3V RS-485 transceivers manufactured by Analog Devices / Maxim Integrated. The series offers various configurations including half-duplex options and selectable slew rates. The MAX3071E specifically provides full-duplex operation with fixed 250kbps performance.

Replacement Considerations

The MAX3070E and MAX3072E are pin-compatible alternatives within the same series. The MAX3070E shares identical electrical characteristics but may differ in package availability. Verify thermal and mechanical specifications when substituting.
