4031A/BEA

Overview

The Rochester Electronics JM38510/17403BEA is a military-grade 6-bit bus driver belonging to the 4000/14000/40000 series. It features inverted outputs and three-state logic capabilities within a ceramic dual in-line package (CDIP-16). The device operates across an extended temperature range from -55 °C to +125 °C, ensuring reliability in harsh environments. This component serves as a high-performance interface solution for demanding digital applications requiring robust signal driving and isolation.

Feature Summary

• Provides six independent inverted output channels for bus interfacing
• Incorporates three-state output capability for effective bus isolation
• Constructed with a hermetically sealed ceramic metal-sealed cofired package
• Designed for operation in extreme temperature conditions up to 125 °C

Applications

• Military aerospace avionics systems
• Harsh environment industrial control interfaces
• High-reliability data bus drivers
• Spacecraft communication subsystems

Procurement Notes

Verify the specific suffix BEA against the original manufacturer datasheet to confirm exact electrical tolerances and pinout compatibility. Ensure the CDIP-16 ceramic package matches your PCB footprint requirements. Confirm that leaded construction meets your assembly process standards, as this part is not RoHS compliant. Validate thermal management strategies for the specified operating temperature range.

Selection Notes

Select this component when a ruggedized, military-specification bus driver is required for critical systems. The ceramic package offers superior environmental protection compared to plastic alternatives. Consider the inverted output polarity during logic design to ensure correct signal alignment. Verify that the three-state functionality integrates properly with your existing bus architecture without causing contention issues.

Part Context

Rochester Electronics specializes in sourcing and supporting obsolete and hard-to-find semiconductors. This part falls under their portfolio of legacy logic devices, maintaining supply continuity for components no longer actively manufactured by original vendors. The JM38510 designation indicates its origin as a military standard microcircuit, now managed by Rochester for long-term availability.

Replacement Considerations

Direct substitutes include other manufacturers' versions of the JM38510/17403BEA or equivalent 4000-series bus drivers in CDIP-16 packages. Verify pin compatibility and electrical specifications before substitution. Generic CMOS equivalents may lack the required military qualification and hermetic sealing.
