100155DC

Overview

The National Semiconductor 100155DC is a high-speed digital logic component belonging to the company's legacy product portfolio. As an integrated circuit manufactured by National Semiconductor, it was designed for specific digital signal processing and logic control applications prior to the company's acquisition by Texas Instruments. The device operates within standard digital logic voltage ranges typical of its era, providing reliable performance for fixed-function logic tasks in industrial and consumer electronic systems.

Feature Summary

• High-speed digital logic operation for efficient signal processing
• Integrated circuit design for compact board integration
• Robust performance suitable for demanding digital environments

Applications

• Industrial control systems requiring reliable logic functions
• Consumer electronics utilizing legacy digital interfaces
• Telecommunications equipment with established logic requirements

Procurement Notes

Verify current availability status as this component originates from National Semiconductor, which was acquired by Texas Instruments. Confirm that the part number matches exact specifications required for your design, as legacy components may have limited production runs or be subject to obsolescence notices. Ensure compatibility with existing system architectures before procurement.

Selection Notes

Select this component only if your design specifically requires the functional characteristics of the National Semiconductor 100155DC. Consider the long-term supply chain stability given the manufacturer's acquisition history. Evaluate whether modern equivalents from Texas Instruments offer improved performance or availability while maintaining pin compatibility and logical functionality for your application.

Part Context

National Semiconductor was a prominent American semiconductor company known for analog and mixed-signal circuits until its acquisition by Texas Instruments in 2011. The 100155DC represents a legacy product from this period, reflecting the technological standards and manufacturing capabilities of the pre-acquisition era. These parts remain relevant in maintenance and retrofit scenarios for older electronic systems.

Replacement Considerations

Consult Texas Instruments documentation for potential cross-reference options or updated equivalents. Verify if newer generations of logic ICs provide backward compatibility. Check for any changes in electrical characteristics or package dimensions that might affect existing PCB layouts.
