MAX3076EASD+

Overview

The MAX3076EASD+ is a full-duplex RS-485 transceiver operating from a single 3.3V supply. It features one driver and one receiver with no slew-rate limiting, supporting data rates up to 16Mbps. 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 DE and RE pins. It operates within an industrial temperature range of -40°C to +125°C in a 14-pin SOIC package.

Feature Summary

• Hot-swap input structure prevents false bus transitions during power-up or insertion
• Fail-safe receiver guarantees a logic-high output under open or shorted input conditions
• Unlimited driver slew rate enables high-speed transmission up to 16Mbps
• Robust protection against electrostatic discharge on all communication pins

Applications

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

Procurement Notes

Verify the specific suffix 'ASD+' corresponds to the required 14-pin SOIC package and the extended -40°C to +125°C temperature grade. Confirm that the full-duplex configuration aligns with system requirements, as other variants in this family support half-duplex operation. Ensure compatibility with the 3.3V logic levels used in the target application design.

Selection Notes

Select this component when high-speed data transmission up to 16Mbps is required without slew-rate limitations. It is suitable for applications needing robust ESD protection and fail-safe behavior on RS-485 buses. Verify that the full-duplex architecture matches the bidirectional communication needs, distinguishing it from half-duplex models like the MAX3078E.

Part Context

This device belongs to the MAX3070E–MAX3079E family of +3.3V RS-485 transceivers. Unlike the MAX3073E or MAX3074E which limit slew rates for lower speeds, the MAX3076E provides unrestricted driver speed. It shares the same pinout and core protection features as siblings like the MAX3077E but is specifically optimized for maximum throughput in full-duplex environments.

Replacement Considerations

The MAX3077EASA+ serves as a direct functional substitute within the same family, offering identical 16Mbps full-duplex performance and pinout compatibility.
