MAX3082EESA+

Overview

The MAX3082EESA+ is a half-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +5V supply (4.75V to 5.25V) and supports data rates up to 115kbps with slew-rate-limited drivers. The device features ±15kV ESD protection, fail-safe circuitry ensuring a logic-high output when inputs are open or shorted, and a low-current shutdown mode drawing 1nA. It utilizes an 8-pin SOIC package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Slew-rate limiting minimizes electromagnetic interference and reduces signal reflections for error-free transmission
• Fail-safe receiver guarantees a logic-high output state during input disconnection or short-circuit conditions
• Enhanced electrostatic discharge protection rated at ±15kV on all I/O pins using the Human Body Model

Applications

• RS-422 and RS-485 communication networks
• Industrial control local area networks
• Transceivers designed for EMI-sensitive applications

Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm that the specific ordering suffix matches the required package type and temperature rating. Ensure compliance with relevant RoHS directives before integration into production systems.

Selection Notes

Select this model specifically for half-duplex RS-485 applications requiring reduced electromagnetic emissions. The integrated slew-rate limiting makes it suitable for long cable runs where signal integrity is critical. Verify that the system power supply remains stable within the specified 5V tolerance range.

Part Context

This component belongs to the MAX3080E–MAX3089E family of high-speed transceivers. While sharing similar pinouts and core functionalities with other members like the MAX3085E, the MAX3082E is distinctively configured for half-duplex operation with fixed 115kbps slew-rate limitations.

Replacement Considerations

The datasheet indicates pin compatibility with the industry-standard 75180 transceiver. Designers should verify that any substitute component maintains identical pin assignments and electrical characteristics to ensure seamless board-level replacement.
