MAX3076EEPD

Overview

The MAX3076EEPD is a full-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc. (Maxim Integrated). It operates on a single 3.3V supply and supports data rates up to 16Mbps with unrestricted slew rates. The device features ±15kV ESD protection on the bus pins, fail-safe receiver inputs that guarantee a logic-high output when inputs are open or shorted, and hot-swap capability to prevent false transitions during power-up. It utilizes a 14-pin SOIC package.

Feature Summary

• Full-duplex communication architecture supporting simultaneous transmission and reception
• Hot-swap functionality eliminates false bus transitions during insertion or power-up
• Fail-safe receiver design ensures a high logic state if differential inputs are unconnected

Applications

• Industrial control networks requiring robust RS-485 connectivity
• Building automation systems utilizing RS-422/RS-485 protocols
• Data acquisition systems operating in electrically noisy environments

Procurement Notes

Verify the specific suffix 'E' indicates industrial temperature range operation (-40°C to +85°C) and lead-free status per manufacturer documentation. Confirm pinout compatibility for the 14-pin SOIC package against existing PCB layouts. Check current lifecycle status as legacy Maxim products may have limited availability or obsolescence notices.

Selection Notes

Select this component for applications requiring full-duplex operation at speeds up to 16Mbps. Ensure the system voltage matches the 3.3V requirement. Consider the ADM3076EYRZ as a potential alternative from Analog Devices for similar specifications if sourcing constraints exist, verifying package and feature parity before substitution.

Part Context

This part belongs to the MAX307x family of low-power, fail-safe transceivers designed for RS-485 and RS-422 communications. The MAX3076 variant specifically distinguishes itself within the series by offering unrestricted driver slew rates, enabling higher data throughput compared to slew-rate-limited siblings like the MAX3070 or MAX3073.

Replacement Considerations

The ADM3076EYRZ is a documented equivalent from Analog Devices featuring identical 16Mbps full-duplex capabilities and 14-pin SOIC packaging. Verify that the replacement maintains the same fail-safe and hot-swap characteristics required by the original design.
