MAX3086EESD+T

Overview

The MAX3086EESD+T is a full-duplex RS-422/RS-485 transceiver manufactured by Analog Devices Inc. (Maxim Integrated). It operates on a single +5V supply with a voltage range of 4.75V to 5.25V and supports data rates up to 10Mbps. The device features ±15kV ESD protection on all I/O pins, fail-safe receiver circuitry, and low-power shutdown mode drawing 1µA typical current. It utilizes a 14-pin SOIC package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Full-duplex communication architecture supporting simultaneous transmission and reception
• Enhanced electrostatic discharge protection rated at ±15kV Human Body Model for all inputs and outputs
• Fail-safe receiver design ensuring a logic-high output state during open or shorted bus conditions

Applications

• RS-422 and RS-485 serial communication networks
• Industrial control local area networks
• EMI-sensitive applications requiring high-speed data transfer

Procurement Notes

Verify the specific suffix 'ESD+T' against official documentation to confirm the presence of lead-free RoHS compliance and tape-and-reel packaging configuration. Ensure the component matches the specified industrial temperature grade (-40°C to +85°C) required for the target application environment.

Selection Notes

Select this component when full-duplex operation is mandatory alongside high-speed transmission capabilities up to 10Mbps. It is suitable for systems requiring robust ESD protection without external components. Verify that the 14-pin SOIC footprint aligns with the PCB layout constraints and that the +5V power supply rail meets the specified operating voltage requirements.

Part Context

This part belongs to the MAX3080E–MAX3089E family of high-speed transceivers. While pin-compatible with industry-standard devices like the 75180, it incorporates enhanced ESD protection and fail-safe features. The MAX3086E specifically provides unrestricted driver slew rates for maximum speed, distinguishing it from slew-rate-limited variants in the same series.

Replacement Considerations

Direct pin-compatible replacements include other members of the MAX308x series such as the MAX3080E or MAX3083E, provided the specific duplex mode and slew-rate limitations match the system requirements.
