JM38510/30701SEA

Overview

The Texas Instruments JM38510/30701SEA is a military-grade decoder/demultiplexer manufactured under the SN54S138 specification. It features a 16-pin Ceramic Dual In-Line Package (CDIP) with an operating temperature range of -55°C to 125°C. The device functions as a 3-line to 8-line decoder, providing eight active-low outputs selected by three binary address inputs and three enable inputs.

Feature Summary

• Provides decoding functionality for three binary address lines into eight distinct active-low output channels
• Includes three independent enable inputs to control data flow and output activation states
• Constructed in a hermetically sealed ceramic dual in-line package designed for high reliability

Applications

• Military and defense electronic systems requiring radiation-hardened or high-reliability logic components
• Space-based applications utilizing QML certified ceramic packaging
• Industrial control systems operating within extended temperature environments

Procurement Notes

Verify that the specific part number matches the required military qualification standards and ceramic package configuration. Confirm RoHS exemption status and lead finish specifications prior to ordering. Ensure compatibility with existing board layouts for the 16-pin CDIP footprint. Validate that the component meets all necessary environmental testing requirements for the intended operational environment.

Selection Notes

Select this component when a high-speed S-TTL decoder is required for harsh environments. Compare against LS-series variants if lower power consumption is prioritized over switching speed. Verify that the 16-pin CDIP package aligns with available socketing or direct soldering infrastructure. Consider thermal management requirements associated with ceramic packages in enclosed assemblies.

Part Context

This part belongs to the SN54 series of high-speed TTL logic devices produced for military specifications. It corresponds to the commercial SN74S138 function but utilizes robust ceramic construction. The device is part of a broader family of decoders and demultiplexers used in complex digital addressing schemes.

Replacement Considerations

JM38510/30701BEA and JM38510/30701BFA are confirmed substitutes offering identical logical functionality in alternative package formats.
