MAX3082ESA+

Overview

The MAX3082ESA+ is a half-duplex RS-485/RS-422 transceiver featuring fail-safe circuitry and slew-rate-limited drivers. It supports data rates up to 115kbps with a single +5V supply (4.75V to 5.25V). The device includes one driver and one receiver, drawing 375µA quiescent current. It offers thermal shutdown protection and operates within the -40°C to +85°C temperature range in an 8-pin SOIC package.

Feature Summary

• Fail-safe design ensures logic-high receiver output when inputs are open or shorted
• Slew-rate-limited drivers minimize electromagnetic interference and signal reflections
• Thermal shutdown protects against excessive power dissipation

Applications

• RS-422/RS-485 communications
• EMI-sensitive applications
• Industrial-control local area networks

Procurement Notes

Verify the specific suffix 'ESA+' corresponds to the required operating temperature range (-40°C to +85°C) and 8-pin SOIC packaging. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement specifications.

Selection Notes

Select this component for half-duplex systems requiring error-free transmission at speeds up to 115kbps. Ensure the application benefits from reduced EMI via slew-rate limiting. Verify that the 1/8-unit-load input impedance allows for the desired number of devices on the bus.

Part Context

This part belongs to the MAX3080–MAX3089 family of high-speed transceivers designed for RS-485/RS-422 communication. It shares common features like fail-safe operation and low-power shutdown with siblings such as the MAX3085 and MAX3088, differing primarily in duplex mode and slew-rate configuration.

Replacement Considerations

The MAX3082EESA-T is a tape-and-reel variant of the same functional device. Cross-reference pinouts and electrical characteristics carefully when substituting.
