MAX3082EESA+T

Overview

The MAX3082EESA+T is a half-duplex RS-485/RS-422 transceiver in a 14-pin SO package, operating from -40°C to +85°C. It features ±15kV ESD protection and fail-safe circuitry guaranteeing a logic-high receiver output when inputs are open or shorted. The device incorporates reduced slew-rate drivers to minimize EMI and reflections, supporting error-free data transmission up to 115kbps. It typically draws 375µA of supply current and supports up to 256 transceivers on the bus due to its 1/8-unit-load receiver input impedance.

Feature Summary

• Fail-safe receiver guarantees a logic-high output when inputs are open or shorted
• Reduced slew-rate drivers minimize electromagnetic interference and signal reflections
• Enhanced electrostatic discharge protection rated at ±15kV using the Human Body Model

Applications

• RS-422/RS-485 communications
• Level translators
• Transceivers for EMI-sensitive applications
• Industrial-control local area networks

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm temperature range and packaging details. Ensure the component matches the required half-duplex configuration and slew-rate limitations for the target application environment.

Selection Notes

Select this component for half-duplex RS-485/RS-422 systems requiring high noise immunity and low electromagnetic emissions. It is suitable for applications where data rates do not exceed 115kbps and extended industrial temperature ranges are necessary.

Part Context

This part belongs to the MAX3080E–MAX3089E family of high-speed transceivers. It shares pin compatibility with industry-standard parts like the 75180 but includes additional internal features implemented via specific pins to enhance performance and reliability in harsh environments.

Replacement Considerations

Pin-compatible with the 75180. Verify functional equivalence regarding slew-rate limiting and fail-safe thresholds before substitution.
