100181FC

Overview

The 100181FC is a specialized logic integrated circuit manufactured by National Semiconductor, belonging to the 100K Series. It functions as an Arithmetic Logic Unit (ALU) designed for binary-coded decimal (BCD) operations with a 4-bit data width. The component is housed in a 24-lead Flatpack package, specifically identified as SMD-24Q-CERPAK, which facilitates surface-mount technology integration into electronic assemblies.

Feature Summary

• Performs arithmetic and logical operations on 4-bit BCD data inputs
• Integrated within the National Semiconductor 100K Series logic family
• Designed for surface-mount assembly using a 24-lead flatpack ceramic package

Applications

• Digital arithmetic processing circuits
• Specialized logic control systems requiring BCD computation
• Industrial or military-grade electronic equipment utilizing the 100K series

Procurement Notes

Verify the manufacturer origin, as National Semiconductor assets were acquired by Texas Instruments. Confirm the specific package variant matches the 24-lead CERPAK specification. Ensure the part number corresponds to the original National Semiconductor designation rather than any subsequent rebranding or alternate sourcing channels.

Selection Notes

Select this component when a dedicated 4-bit BCD ALU from the 100K series is required. Consider the 24-lead flatpack footprint for PCB layout compatibility. Verify that the operating environment aligns with the specifications of legacy National Semiconductor logic devices.

Part Context

This component is part of the National Semiconductor 100K Series, a line of high-reliability logic devices often utilized in demanding applications. The 100181FC specifically addresses arithmetic logic needs within this family, providing a fixed-function solution for BCD calculations without requiring complex programming.

Replacement Considerations

Consult official datasheets for direct pin-compatible substitutes within the 100K series. Cross-reference with Texas Instruments documentation, as they hold the rights to the former National Semiconductor product lines.
