MAX3077EESA+

Overview

The MAX3077EESA+ is a full-duplex RS-485 transceiver operating from a single 3.3V supply. It features one driver and one receiver with data rates up to 16Mbps. The device includes ±15kV ESD protection on I/O pins, true fail-safe circuitry, and hot-swap capability for the DE and RE inputs. Supply current is typically 1.5mA. It operates within an industrial temperature range of -40°C to +85°C and is housed in an 8-pin SOIC package.

Feature Summary

• Hot-swap input structure prevents false transitions during power-up or bus insertion
• True fail-safe receiver guarantees logic-high output when inputs are open or shorted
• Unlimited slew-rate drivers support high-speed transmission up to 16Mbps

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature rating. Confirm RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Ensure the component matches the required full-duplex configuration for the target application design.

Selection Notes

Select this component for applications requiring full-duplex communication at speeds up to 16Mbps. It is suitable for environments needing robust ESD protection and fail-safe operation without shutdown mode functionality. Verify that the 3.3V supply voltage aligns with the system power architecture and that the SOIC-8 package fits the PCB layout constraints.

Part Context

The MAX3077EESA+ belongs to the MAX3070E–MAX3079E family of 3.3V RS-485 transceivers. This series provides various options for duplex modes and data rates. The MAX3077E specifically offers full-duplex operation with unrestricted driver slew rates, distinguishing it from slew-rate-limited variants like the MAX3070E or half-duplex models like the MAX3072E.

Replacement Considerations

ADM3077EYRZ is a verified equivalent offering identical 16Mbps full-duplex performance and 3.3V operation.
