MAX3087EEPA+

Overview

The MAX3087EEPA+ is a full-duplex RS-422/RS-485 transceiver featuring one driver and one receiver. It supports data rates up to 10Mbps with an operating supply voltage range of 4.75V to 5.25V. The device provides ±15kV ESD protection on all I/O pins and incorporates fail-safe circuitry that guarantees a logic-high receiver output when inputs are open or shorted. It operates within a temperature range of -40°C to +85°C, draws 600µA typical supply current, and is housed in an 8-pin PDIP package.

Feature Summary

• Full-duplex communication architecture supporting simultaneous transmission and reception
• Fail-safe receiver design ensuring high logic state during bus idle conditions
• Robust electrostatic discharge protection rated at ±15kV for Human Body Model

Applications

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

Procurement Notes

Verify the specific suffix EEPA against official manufacturer documentation to confirm the exact package type, pin configuration, and temperature rating. Confirm RoHS compliance status through authorized distributors. Ensure the component matches the required full-duplex specification for your system design.

Selection Notes

Select this component for applications requiring full-duplex operation at speeds up to 10Mbps. It is suitable for environments needing robust ESD protection and fail-safe behavior. Verify compatibility with standard 5V logic levels and ensure the 8-pin DIP package fits the target PCB layout constraints.

Part Context

This part belongs to the MAX3080E–MAX3089E family of high-speed transceivers. While sharing core features like ESD protection and fail-safe logic, it differs from half-duplex variants (e.g., MAX3088E) by utilizing separate transmit and receive lines. It also lacks the programmable slew-rate selection found in the MAX3089E.

Replacement Considerations

The MAX3087ESA+ serves as a surface-mount equivalent offering identical electrical performance in an SOIC package. Other family members like the MAX3086E provide similar specifications but may differ in package availability or minor thermal characteristics.
