MAX487MJA

Drivers, Receivers, Transceivers Overview

The MAX487MJA is a military-grade, low-power transceiver designed for RS-485 and RS-422 communication protocols. It integrates one driver and one receiver within a single package. The device features slew-rate-limited drivers to minimize electromagnetic interference (EMI) and reduce signal reflections on improperly terminated cables. This design supports error-free data transmission at rates up to 250 kbps. It operates from a single 5 V supply with a typical quiescent current of 120 µA. The component is qualified under MIL-STD-883 standards and housed in an 8-CDIP package.

Drivers, Receivers, Transceivers Feature Summary

• Slew-rate-limited drivers minimize EMI and reflections for reliable data transmission
• Military qualification compliant with MIL-STD-883 standards
• Low-power operation with reduced quiescent current consumption

Drivers, Receivers, Transceivers Applications

• Military communication bus systems requiring high reliability
• Industrial control networks operating in harsh environments
• RS-485/RS-422 multi-point data transmission links

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix MJA indicates military grade qualification and ceramic DIP packaging. Confirm the datasheet revision matches the required environmental specifications. Check for lead-free status if RoHS compliance is mandatory for the assembly process. Ensure the supplier provides traceability documentation for military-grade components.

Drivers, Receivers, Transceivers Selection Notes

Select this component when military reliability and low power consumption are critical. It is suitable for applications requiring 250 kbps data rates over RS-485 or RS-422 buses. Compare against commercial variants like the MAX487CUA if military qualification is not required. Consider the 8-CDIP package constraints for PCB layout and thermal management.

Drivers, Receivers, Transceivers Part Context

The MAX487 belongs to the Maxim Integrated family of low-power, slew-rate-limited RS-485/RS-422 transceivers. This series includes similar parts such as the MAX481, MAX483, MAX485, MAX488, and MAX489. These devices share common functional characteristics but differ in pinout configurations, voltage ranges, and package options. The MAX487 specifically offers a standard half-duplex configuration.
