MAX3087EESA+

Overview

The MAX3087EESA+ is a full-duplex RS-422/RS-485 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 10Mbps with unrestricted slew rates. The device contains one driver and one receiver, featuring ±15kV ESD protection on all I/O pins and fail-safe circuitry that guarantees a logic-high receiver output when inputs are open or shorted. It draws 600µA maximum supply current and operates within a temperature range of -40°C to +85°C in an 8-pin SOIC package.

Feature Summary

• Fail-safe receiver circuitry ensures a logic-high output during bus idle states or input faults
• Enhanced electrostatic discharge protection rated at ±15kV for robust industrial environments
• Unrestricted driver slew rate enables high-speed communication up to 10Mbps
• Thermal shutdown and short-circuit protection safeguard the driver outputs

Applications

• RS-422 and RS-485 communications networks
• Industrial-control local area networks
• EMI-sensitive applications requiring high-speed data transmission

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm exact packaging and temperature grade. Confirm RoHS compliance status through authorized distributors. Ensure the component matches the required full-duplex configuration before procurement.

Selection Notes

Select this component for full-duplex applications requiring 10Mbps transmission speeds. Unlike slew-rate-limited variants, this model does not restrict edge rates. Verify that the system design accommodates the resulting electromagnetic interference characteristics associated with fast switching edges.

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 enhanced features such as superior ESD protection and fail-safe logic. The 'E' designation indicates the extended industrial temperature range.

Replacement Considerations

Pin-compatible alternatives include other members of the MAX308x series, such as the MAX3086E or MAX3088E. Note that these may differ in duplex mode or slew-rate limiting capabilities.
