MAX3087EPA

Overview

The MAX3087EPA is a single RS-422/RS-485 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It supports data rates up to 10 Mbps with slew-rate limiting to reduce electromagnetic interference. The device operates on a single 5 V supply, drawing 600 µA of quiescent current. It features 15 kV ESD protection and fail-safe receiver inputs that default to a logic-high state when the bus is idle. The component is housed in an 8-pin PDIP package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Fail-safe receiver design ensures a high logic state during idle or disconnected bus conditions
• Integrated slew-rate limiting minimizes signal reflections and reduces radiated emissions
• Robust electrostatic discharge protection rated at 15 kV for harsh industrial environments

Applications

• Fieldbus networks requiring reliable half-duplex communication
• Industrial automation systems with high noise immunity needs
• Building automation control panels

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm pinout compatibility and electrical specifications. Ensure the procurement channel provides traceable source material to validate authenticity. Cross-reference the ordering information with the latest datasheet to avoid discrepancies in package type or temperature grade.

Selection Notes

Select this component for applications requiring high-speed serial communication over twisted-pair lines. The 10 Mbps rate suits bandwidth-intensive protocols. The PDIP package facilitates prototyping and through-hole assembly. Verify that the system power supply remains stable at 5 V to maintain optimal signal integrity and low power consumption.

Part Context

This part belongs to the MAX308x series of high-speed RS-422/RS-485 transceivers. It shares functional similarities with other members like the MAX3087ESA but differs in packaging. The series is designed for robust communication in electrically noisy environments, offering a balance of speed and power efficiency.

Replacement Considerations

The MAX3087ESA+ serves as a surface-mount alternative within the same family. Verify pin-to-pin compatibility before substitution. Ensure the replacement matches the required operating temperature range and package constraints of the target application.
