JM38510/07701BEA

Overview

JM38510/07701BEA is a military-grade 3-line to 8-line decoder/demultiplexer manufactured by Texas Instruments. It operates within a temperature range of -55°C to 125°C and utilizes a 16-pin ceramic dual in-line package (CDIP). The component is part of the SN54S138 series, designed for high-speed logic applications requiring robust environmental tolerance and reliability standards suitable for defense and aerospace systems.

Feature Summary

• Military-grade qualification for harsh environments
• High-speed S-TTL logic family performance
• Three independent enable inputs for complex control
• Ceramic metal-sealed packaging for radiation resistance

Applications

• Aerospace command and data handling systems
• Defense communication equipment address decoding
• Military computer memory addressing circuits
• Harsh environment industrial control logic

Procurement Notes

Verify QML certification status and specific lot traceability requirements before procurement. Confirm that the CDIP package variant matches the mechanical constraints of the target assembly. Ensure compliance with relevant military specifications and environmental testing standards applicable to the deployment scenario.

Selection Notes

Select this component when military reliability and wide temperature operation are mandatory. Compare against commercial SN74LS138 variants if cost is primary and environmental exposure is limited. Verify pinout compatibility with existing board layouts designed for standard 16-pin DIP footprints.

Part Context

This part belongs to the SN54 series of logic devices, which are distinguished from the SN74 series by their extended temperature ranges and higher reliability standards. The JM38510 prefix indicates a specific military procurement designation managed under Department of Defense standards, ensuring consistent quality across production batches.

Replacement Considerations

SNJ54S138J serves as a direct equivalent in the same package type. SN54LS138 offers lower power consumption but different switching characteristics. Verify electrical parameters and pin compatibility before substituting with commercial grade alternatives.
