MAX3080EEPD+

Overview

The MAX3080EEPD+ is a full-duplex RS-422/RS-485 transceiver in a 14-pin Plastic DIP package. It operates from a single +5V supply (4.75V to 5.25V) with a typical quiescent current of 375µA and supports data rates up to 115kbps. The device features ±15kV ESD protection on all I/O pins, fail-safe receiver circuitry guaranteeing a logic-high output when inputs are open or shorted, and reduced slew-rate drivers to minimize EMI. It includes thermal shutdown protection and low-current shutdown mode.

Feature Summary

• Fail-safe receiver circuitry ensures a logic-high output state when differential inputs are open or shorted.
• Enhanced ESD protection rated at ±15kV Human Body Model for all driver and receiver pins.
• Reduced slew-rate limiting minimizes electromagnetic interference and reflections on improperly terminated cables.
• Thermal shutdown circuitry protects the driver outputs by forcing them into a high-impedance state during excessive power dissipation.

Applications

• RS-422 and RS-485 communication networks
• Industrial control local area networks
• EMI-sensitive applications requiring error-free transmission

Procurement Notes

Verify the specific suffix 'EEPD+' against official documentation to confirm the exact temperature range (-40°C to +85°C), package type (Plastic DIP), and RoHS compliance status. Ensure that the ordering information matches the manufacturer's current datasheet revision to avoid discrepancies in pinout or electrical characteristics.

Selection Notes

Select this component for full-duplex applications requiring robust ESD protection and fail-safe operation. It is suitable for environments where cable termination may be imperfect due to its slew-rate limiting features. Verify that the required data rate does not exceed 115kbps, as higher speeds require different variants within the MAX3080E family.

Part Context

This part belongs to the MAX3080E–MAX3089E series of high-speed transceivers designed for RS-485/RS-422 communication. The series offers various configurations including half-duplex options and selectable slew rates. The MAX3080E specifically provides fixed full-duplex operation with limited slew rates optimized for lower speed, noise-immune transmissions.

Replacement Considerations

The datasheet notes pin compatibility with the industry-standard 75180 transceiver. Designers replacing legacy components should verify that the 75180's electrical parameters align with the MAX3080E's specifications, particularly regarding ESD tolerance and fail-safe thresholds.
