MAX3081EEPA

Overview

The MAX3081EEPA is a full-duplex RS-485/RS-422 transceiver featuring one driver and one receiver. It operates on a single +5V supply (4.75V to 5.25V) with a typical quiescent current of 375µA. The device provides ±15kV ESD protection on all I/O pins and incorporates fail-safe circuitry that guarantees a logic-high receiver output when inputs are open or shorted. Designed for reduced electromagnetic interference, it supports data transmission rates up to 115kbps via slew-rate limiting. The component is housed in an 8-pin Plastic DIP package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Fail-safe receiver circuitry ensures a logic-high output state during bus idle conditions or input disconnection.
• Slew-rate-limited drivers minimize electromagnetic interference and signal reflections on improperly terminated cables.
• Enhanced electrostatic discharge protection rated at ±15kV using the Human Body Model across all communication pins.

Applications

• RS-422 and RS-485 serial communication networks
• Industrial control local area networks
• Level translation interfaces

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature rating. Confirm RoHS compliance status through manufacturer declarations. Ensure the source document matches the exact part number to validate electrical characteristics and pinout configurations before procurement.

Selection Notes

Select this component for applications requiring full-duplex communication with low power consumption. The integrated fail-safe feature simplifies bus management by preventing undefined states. Verify that the required data rate does not exceed 115kbps, as higher speeds require different variants within the MAX3080E family.

Part Context

This device belongs to the MAX3080E–MAX3089E series of high-speed transceivers. While sharing similar core architecture and ESD protection levels, other models in the series offer half-duplex operation, selectable slew rates, or programmable phase controls. The MAX3081E specifically targets full-duplex applications with fixed low-speed performance.

Replacement Considerations

The MAX3080E and MAX3083E are pin-compatible full-duplex alternatives. The MAX3080E offers identical functionality but may differ in manufacturing lot specifications. Cross-referencing datasheets is required to ensure interface compatibility.
