M38510/30702SEA

Overview

The M38510/30702SEA is a military-grade decoder/demultiplexer manufactured by Texas Instruments. It operates within a temperature range of -55 to 125 °C and utilizes a ceramic dual in-line package (CDIP) with 16 pins. The device is RoHS non-compliant and features SnPb lead finish. It is classified under the LS logic series, functioning as a 2-to-4 line decoder or demultiplexer.

Feature Summary

• Provides decoding and demultiplexing capabilities for digital logic circuits
• Constructed with a hermetically sealed ceramic package for environmental protection
• Designed for high reliability in demanding operational environments

Applications

• Military and defense electronic systems
• Aerospace avionics control units
• Harsh environment data routing applications

Procurement Notes

Verify that the specific order matches the M38510/30702SEA designation to ensure correct CDIP packaging and military qualification status. Confirm RoHS exemption requirements are met prior to procurement. Validate that the supplier provides traceability documentation consistent with MIL-M-38510 standards. Ensure storage conditions align with the specified moisture sensitivity level for ceramic packages.

Selection Notes

Select this component when a ruggedized, military-specification decoder is required for mission-critical applications. The LS series offers standard propagation delays suitable for general-purpose logic interfacing. Consider the 16-pin CDIP form factor for through-hole mounting in shielded enclosures. Evaluate thermal management needs given the wide operating temperature range.

Part Context

This part belongs to the SN54LS139A family, which includes commercial and space-qualified variants. The M38510 prefix indicates compliance with MIL-M-38510 specifications for integrated circuits. It serves as a specialized version of the standard LS139A decoder, tailored for extended durability and strict manufacturing controls.

Replacement Considerations

Direct substitutes include other M38510/30702 variants such as M38510/30702BEA or M38510/30702BFA, depending on preferred package style. Commercial equivalents like SN74LS139AN lack the necessary environmental ratings.
