MAX3076EEPD+

Overview

The MAX3076EEPD+ is a full-duplex RS-485 transceiver operating from a single +3.3V supply. It features one driver and one receiver with ±15kV ESD protection on I/O pins. The device supports data transmission speeds up to 16Mbps with unrestricted slew rates. It incorporates fail-safe circuitry that guarantees a logic-high receiver output when inputs are open or shorted. Hot-swap capability prevents false transitions during board insertion. The component operates within a temperature range of -40°C to +85°C and draws 800μA in unloaded conditions.

Feature Summary

• Hot-swap input structure on DE and RE pins eliminates false bus transitions during power-up or hot insertion.
• True fail-safe receiver ensures a logic-high output when receiver inputs are open, shorted, or disconnected.
• Unrestricted driver slew rate enables error-free data transmission at speeds up to 16Mbps.
• Provides ±15kV Human Body Model ESD protection on all I/O pins for robust performance.

Applications

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

Procurement Notes

Verify the specific package configuration against the datasheet pinout diagrams before integration. Confirm that the thermal management requirements align with the specified derating curves for the selected enclosure. Ensure the design accounts for the 3.3V supply tolerance and bypass capacitor placement as detailed in the application information section of the official documentation.

Selection Notes

Select this component for applications requiring full-duplex communication without slew-rate limitations. It is suitable for environments where hot-swap functionality is necessary to prevent bus contention. Verify compatibility with the system's voltage levels and ensure the load impedance does not exceed the 1/8-unit load specification for proper bus termination.

Part Context

This part belongs to the MAX3070E–MAX3079E family of high-speed RS-485 transceivers manufactured by Analog Devices / Maxim Integrated. The series offers various configurations including half-duplex options and selectable slew rates. The MAX3076 variant specifically provides full-duplex operation with maximum speed capabilities.

Replacement Considerations

Compatible substitutes within the same family include the MAX3077E and MAX3078E, which share similar electrical characteristics and pinouts. Verify package availability and thermal specifications when considering these alternatives.
