MAX3071EAPA+

Overview

The MAX3071EAPA+ is a +3.3V, full-duplex RS-485 transceiver featuring one driver and one receiver in an 8-pin PDIP package. It supports data rates up to 250kbps with enhanced slew-rate limiting to minimize EMI. The device includes ±15kV Human Body Model ESD protection on I/O pins, true fail-safe circuitry ensuring a logic-high output when inputs are open or shorted, and hot-swap capability on DE and RE inputs. Operating temperature ranges from -40°C to +125°C.

Feature Summary

• Full-duplex communication architecture with dedicated transmit and receive paths
• Enhanced slew-rate limiting for error-free transmission up to 250kbps
• Integrated hot-swap input structure on enable pins to prevent bus contention during insertion

Applications

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

Procurement Notes

Verify the specific suffix 'EAPA+' against official documentation to confirm the PDIP package type and industrial temperature range (-40°C to +125°C). Ensure compatibility with existing board layouts designed for 8-pin through-hole configurations. Cross-reference the manufacturer's latest datasheet revision to confirm pinout consistency and electrical characteristics.

Selection Notes

Select this component for applications requiring full-duplex RS-485 communication at speeds up to 250kbps. It is suitable for environments needing robust ESD protection and fail-safe operation without shutdown mode functionality. Consider alternative models within the MAX307x family if half-duplex operation or higher data rates are required.

Part Context

This part belongs to the MAX3070E–MAX3079E series of +3.3V RS-485/RS-422 transceivers. Unlike other members such as the MAX3075E (half-duplex) or MAX3079E (selectable duplex), the MAX3071E is specifically designated for full-duplex applications. It shares common features like fail-safe receivers and hot-swap inputs with the broader family.

Replacement Considerations

Direct functional replacements include other full-duplex variants from the same series, such as the MAX3070E or MAX3073E, provided package and thermal requirements match. Verify that any substitute maintains the 250kbps maximum data rate and PDIP footprint.
