JM38510/30702BFA

Overview

The JM38510/30702BFA is a military-grade dual 4-line to 16-line decoder/demultiplexer manufactured by Texas Instruments. It operates within a temperature range of -55 °C to 125 °C and utilizes a ceramic flatpack (CFP) package with 16 pins. The device is part of the LS logic series, designed for high-reliability applications requiring robust signal decoding capabilities in harsh environments.

Feature Summary

• Dual independent decoding functionality
• Military-grade reliability certification
• Wide operating temperature capability

Applications

• Military communication systems
• Defense avionics control units
• Harsh environment data routing

Procurement Notes

Verify that the component matches the exact MIL-PRF-38535 Class B specifications required for your system. Confirm the CFP package integrity and pin alignment upon receipt. Ensure storage conditions maintain the specified environmental ratings throughout the supply chain.

Selection Notes

Select this component when dual decoding is necessary within a single package footprint. Consider the LS series speed characteristics against system timing requirements. Evaluate the ceramic package benefits for thermal stability and radiation hardness compared to plastic alternatives.

Part Context

This part belongs to the SN54LS139A family, which includes commercial and space-qualified variants. The JM38510 prefix indicates it is a specific military qualification under the MIL-M-38510 standard, ensuring higher screening and reliability standards than standard catalog parts.

Replacement Considerations

SNJ54LS139AW is a direct functional equivalent in the same CFP package. Verify pin compatibility and electrical parameters before substitution. Other family members may require package adaptation or circuit redesign.
