MAX3087ECSA+T

Overview

The MAX3087ECSA+T is a full-duplex RS-422/RS-485 transceiver featuring one driver and one receiver. It operates on a single +5V supply (4.75V to 5.25V) with a typical quiescent current of 375µA. The device supports data rates up to 10Mbps without slew-rate limiting and includes fail-safe circuitry that guarantees a logic-high receiver output when inputs are open or shorted. It utilizes an 8-pin SOIC package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Fail-safe design ensures a logic-high receiver output during bus idle, open, or shorted conditions.
• High-speed transmission capability reaching 10Mbps with unrestricted driver slew rates.
• Supports high node density by providing a 1/8-unit-load receiver input impedance.

Applications

• RS-422 and RS-485 communication networks
• Industrial control local area networks
• Level translation applications

Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range (0°C to +70°C), while 'E' denotes the extended range (-40°C to +85°C). Confirm the 'SA' package designation corresponds to the narrow SOIC format. Ensure the '+T' suffix matches the required reel packaging configuration for automated assembly processes.

Selection Notes

Select this component for full-duplex applications requiring 10Mbps throughput. It is suitable where standard RS-485 noise immunity is needed via fail-safe thresholds. Consider alternative models if half-duplex operation or lower power consumption is required. Verify that the system voltage remains strictly within the 4.75V to 5.25V operating window.

Part Context

This part belongs to the MAX3080–MAX3089 family of high-speed transceivers designed for RS-422 and RS-485 standards. The series provides various options for duplex modes and slew-rate limitations. The MAX3087 specifically targets full-duplex environments needing high-speed data transfer without the electromagnetic interference constraints of slower slew rates.

Replacement Considerations

The MAX3087ESA+ serves as a direct pin-compatible replacement offering the same electrical specifications but with an extended industrial temperature rating (-40°C to +85°C).
