MAX3071EESA+T

Overview

The MAX3071EESA+T is a +3.3V, full-duplex RS-485 transceiver featuring one driver and one receiver in an SOIC-8 package. It supports data rates up to 250kbps with slew-rate-limited drivers to minimize EMI. The device includes fail-safe circuitry that guarantees a logic-high receiver output when inputs are open or shorted. It provides ±15kV Human Body Model ESD protection on I/O pins and incorporates hot-swap capability on the DE and RE control inputs to prevent false transitions during power-up or bus insertion.

Feature Summary

• Full-duplex communication architecture with integrated fail-safe receiver circuitry
• Slew-rate-limited driver design for reduced electromagnetic interference and signal reflections
• Hot-swap input structure on enable pins to ensure safe board insertion into powered backplanes

Applications

• Industrial Control Systems
• Telecommunications Equipment
• Security Systems
• Lighting Systems
• Instrumentation

Procurement Notes

Verify the specific suffix 'EESA+T' against official Analog Devices documentation to confirm the industrial temperature range (-40°C to +85°C), SOIC-8 narrow package, and lead-free status. Confirm availability through authorized distributors as supply constraints may apply.

Selection Notes

Select this component for applications requiring full-duplex RS-485 communication at speeds up to 250kbps. It is suitable for environments where EMI reduction is critical due to its slew-rate limiting. Note that this specific variant lacks the shutdown mode feature found in other family members like the MAX3070E.

Part Context

This part belongs to the MAX3070E–MAX3079E family of high-speed RS-485/RS-422 transceivers. While sharing core features like ESD protection and fail-safe operation, it is distinguished by its fixed full-duplex configuration and 250kbps maximum data rate capability.

Replacement Considerations

The MAX3070EESA+T serves as a direct functional replacement but offers a shutdown mode not present in the MAX3071E. For higher speed requirements, the MAX3076EESA+T (16Mbps) or MAX3079E (selectable speed/duplex) are alternative options within the same package.
