100123W-MIL

Overview

The 100123W-MIL is a military-qualified, non-inverting buffer integrated circuit manufactured by National Semiconductor. It operates within an ECL-compatible logic family and features three functional elements, each providing two-bit output capability for a total of six bits per element configuration. The device supports a supply voltage range from -4.2V to -5.7V, ensuring stable performance in demanding environments. Designed for high-speed digital systems, it utilizes a 24-lead Ceramic Flatpack (CFP) package suitable for aerospace and defense applications requiring rigorous reliability standards.

Feature Summary

• Military-grade qualification for harsh environment reliability
• Non-inverting buffer architecture with true output signaling
• ECL-compatible operation for high-speed digital processing

Applications

• Aerospace digital signal buffering
• Defense communication system interfaces
• High-reliability computer bus drivers

Procurement Notes

Verify the specific revision level and lot traceability documentation when sourcing this component. Ensure that the supplier provides evidence of military qualification compliance. Confirm the package integrity upon receipt, as ceramic flatpacks require careful handling to prevent lead frame damage. Cross-reference the manufacturer part number with current Rochester Electronics or authorized distributor listings to confirm availability and authenticity.

Selection Notes

Select this component when a non-inverting buffer with ECL compatibility is required for military specifications. Consider the 24-CFP package constraints regarding board space and thermal management. Verify that the input/output voltage levels align with the rest of the ECL logic family in the design. This part is suitable for designs prioritizing radiation hardness and long-term stability over cost optimization.

Part Context

This component belongs to the National Semiconductor MIL/Aero Analog Group portfolio, which specializes in linear and logic devices qualified for military use. The 100123 series represents a line of high-speed ECL buffers designed for critical infrastructure. These parts are often sourced through specialized distributors like Rochester Electronics after original production lines have been discontinued or consolidated.

Replacement Considerations

Check for direct equivalents in the 100123 series from other manufacturers offering military-grade ECL buffers. Verify pin-to-pin compatibility with the 24-CFP footprint. Ensure that any substitute maintains the same non-inverting function and ECL voltage tolerances.
