MAX3087EESA+T

Overview

The MAX3087EESA+T is a full-duplex RS-422/RS-485 transceiver featuring one driver and one receiver in an 8-pin SOIC package. It supports data rates up to 10Mbps with unrestricted slew rates. The device operates on a single +5V supply (4.75V to 5.25V) and draws 600µA typical quiescent current. It includes fail-safe circuitry ensuring a logic-high output when inputs are open or shorted, and provides ±15kV ESD protection on all I/O pins per the Human Body Model.

Feature Summary

• Fail-safe receiver guarantees a logic-high output state when differential inputs are open or shorted
• Enhanced electrostatic discharge protection rated at ±15kV for all RS-485/RS-422 input and output pins
• Unrestricted driver slew rate enables high-speed data transmission up to 10Mbps

Applications

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

Procurement Notes

Verify the component against official Analog Devices documentation to confirm pinout compatibility and electrical specifications. Ensure the operating environment remains within the specified -40°C to +85°C temperature range. Confirm that the power supply voltage stays strictly between 4.75V and 5.25V to maintain reliable operation of the transceiver circuitry.

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, making it suitable for shorter cable runs where signal integrity is maintained without reflection mitigation. Verify that the system design accommodates the standard 1/8-unit-load receiver impedance for bus capacity planning.

Part Context

This device belongs to the MAX3080E–MAX3089E family of high-speed transceivers. While sharing similar packaging and basic interface standards with other members, it is specifically designated for full-duplex operation with maximum speed capabilities. It serves as a direct interface solution for microcontrollers connecting to RS-485/RS-422 buses in industrial environments.

Replacement Considerations

The MAX3086E and MAX3088E are pin-compatible full-duplex alternatives within the same series offering identical 10Mbps performance characteristics.
