100117W-MIL

Overview

The National Semiconductor 100117W-MIL is a military-qualified logic gate belonging to the 100K series. It functions as an OR-AND/OR-AND-Invert gate utilizing ECL technology. The device features a configurable architecture with three independent circuits and a total of twelve inputs, distributed as six pairs of two-input channels. It is housed in a 24-pin Ceramic Dual In-Line Package (CDIP). This component is designed for high-reliability applications requiring specific logic inversion and combination capabilities within harsh environments.

Feature Summary

• Configurable multi-function logic structure supporting OR-AND and OR-AND-Invert operations
• Military-grade qualification ensuring reliability in demanding operational conditions
• ECL technology implementation for high-speed signal processing

Applications

• Spacecraft avionics systems
• Military communication equipment
• High-reliability industrial control logic

Procurement Notes

Verify the manufacturer part number against official National Semiconductor documentation to confirm authenticity. Ensure the package type matches the required 24-CDIP specification. Check for any specific military lot traceability requirements mandated by the end-use application standards before finalizing procurement decisions.

Selection Notes

Select this component when a specific OR-AND or OR-AND-Invert logic function is required within an ECL-based design. The 100K series designation indicates compatibility with standard ECL voltage levels and timing characteristics. Consider the physical dimensions of the CDIP package during PCB layout planning to ensure proper mechanical fit and thermal management.

Part Context

This component is part of National Semiconductor's extensive portfolio of military-qualified analog and digital devices. The 100K series represents a legacy line of high-performance logic gates known for their robustness. As National Semiconductor has undergone corporate changes, verify current support status through authorized distributors or successor entities for long-term supply chain stability.

Replacement Considerations

Consult official cross-reference guides for direct equivalents. Verify pinout compatibility and logical functionality equivalence before substituting. Ensure any replacement maintains the same ECL voltage specifications and radiation hardness requirements if applicable.
