MAX3081EESA+T

Overview

The MAX3081EESA+T is a full-duplex RS-422/RS-485 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 600µA. 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 high-speed communication, it supports data rates up to 10Mbps without slew-rate limiting. It is housed in an 8-pin SOIC package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Fail-safe receiver design ensures a logic-high output state during bus idle conditions or input disconnection.
• Enhanced electrostatic discharge protection rated at ±15kV via the Human Body Model across all interface pins.
• Full-duplex architecture allows simultaneous independent transmission and reception over twisted-pair lines.

Applications

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

Procurement Notes

Verify the component authenticity by checking the manufacturer marking against official documentation. Confirm the specific suffix matches the required package type and temperature rating. Ensure the ordering information aligns with the intended application requirements before finalizing procurement.

Selection Notes

Select this model for full-duplex applications requiring high-speed data transfer up to 10Mbps. It is suitable for environments needing robust ESD protection and fail-safe behavior. Verify compatibility with the system's voltage levels and ensure the 8-pin SOIC footprint fits the PCB layout constraints.

Part Context

This component belongs to the MAX3080E–MAX3089E family of high-speed transceivers. It shares pinout compatibility with industry-standard parts like the 75180 but includes enhanced features such as improved ESD protection and fail-safe logic. The series offers various options for half/full-duplex modes and selectable slew rates.

Replacement Considerations

Pin-compatible alternatives include the MAX3080E and MAX3086E. Verify functional differences regarding duplex mode and slew-rate limitations before substitution. Ensure the replacement part meets the same electrical specifications and environmental ratings.
