MAX3077EESA/GG8

Overview

The MAX3077EESA/GG8 is a +3.3V, full-duplex RS-485/RS-422 transceiver featuring one driver and one receiver. It supports data rates up to 16Mbps with unrestricted slew rates. The device includes ±15kV ESD protection on I/O pins, fail-safe circuitry ensuring a logic-high output when inputs are open or shorted, and hot-swap capability for safe bus insertion. Operating from a single 3.3V supply, it draws 800µA of supply current and accepts up to 256 units on the bus due to its 1/8-unit load receiver input impedance.

Feature Summary

• Full-duplex communication architecture supporting simultaneous transmission and reception
• Hot-swap input structure prevents false transitions during power-up or live bus insertion
• Fail-safe receiver guarantees a logic-high output state under open or shorted input conditions
• Unrestricted driver slew rates enable high-speed data transmission up to 16Mbps

Applications

• Lighting Systems
• Industrial Control
• Telecom
• Security Systems
• Instrumentation

Procurement Notes

Verify the specific ordering suffix GG8 against official manufacturer documentation to confirm package type and tape-and-reel specifications. Confirm that the component matches the exact Analog Devices / Maxim Integrated part number before integration into designs. Cross-reference datasheet revisions to ensure compatibility with existing system requirements.

Selection Notes

Select this component for applications requiring full-duplex RS-485 or RS-422 communication at speeds up to 16Mbps. It is suitable for environments where hot-swap functionality and robust ESD protection are critical. Ensure the design utilizes a 3.3V supply voltage and accommodates the 8-pin SO package dimensions.

Part Context

This device belongs to the MAX3070E–MAX3079E family of +3.3V, ±15kV ESD-protected, fail-safe, hot-swap RS-485/RS-422 transceivers manufactured by Analog Devices / Maxim Integrated. The family offers various configurations including half-duplex options and selectable slew rates, with the MAX3077E specifically designated for full-duplex operation without slew-rate limiting.

Replacement Considerations

Other members of the MAX3070E–MAX3079E family may serve as alternatives if pin compatibility and electrical characteristics align. Verify that substitute parts match the required full-duplex mode and 16Mbps data rate capabilities.
