MAX3076EESD+

Overview

The MAX3076EESD+ is a full-duplex RS-485 transceiver operating from a single 3.3V supply. It features one driver and one receiver with fail-safe circuitry that guarantees a logic-high output when inputs are open or shorted. The device supports data rates up to 16Mbps without slew-rate limiting. It includes ±15kV ESD protection on I/O pins and hot-swap capability for the DE and RE inputs. Supply current is typically 1.5mA, dropping to 10µA in shutdown mode. The component operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Hot-swap input structure prevents false bus transitions during power-up or insertion
• Fail-safe receiver ensures logic-high output under open or shorted input conditions
• High-speed transmission capability up to 16Mbps without slew-rate limitations
• Robust protection against electrostatic discharge events on communication lines

Applications

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

Procurement Notes

Verify the specific suffix 'ESD+' indicates the standard SOIC-14 package variant. Confirm the 'E' designation aligns with the required -40°C to +85°C industrial temperature range. Ensure the ordering information matches the full-duplex configuration intended for the design. Cross-reference the manufacturer's latest documentation for any potential pinout revisions.

Selection Notes

Select this component for applications requiring high-speed full-duplex RS-485 communication at 3.3V. It is suitable for environments demanding robust ESD protection and fail-safe operation. Consider alternative models like the MAX3079E if half-duplex modes or selectable slew rates are required. Verify that the 1/8-unit load impedance supports the necessary node count on the bus.

Part Context

This part belongs to the MAX3070E–MAX3079E family of 3.3V RS-485 transceivers. While sharing common features like fail-safe circuitry and ESD protection, it differs from siblings by offering unrestricted driver slew rates for maximum speed. Unlike the MAX3072E, it is designed specifically for full-duplex applications rather than half-duplex.

Replacement Considerations

The MAX3076EAPD+ serves as a direct replacement using a plastic DIP package. Other family members like the MAX3077E offer identical electrical performance but utilize an 8-pin SOIC package.
