100166DCQR

Overview

The National Semiconductor 100166DCQR is a 9-bit magnitude comparator integrated circuit housed in a 24-CDIP package. It compares two binary numbers, designated as A and B, to determine their relative magnitude. The device features bit-active high outputs that signal when input A is less than, equal to, or greater than input B. This component is designed for digital logic applications requiring precise numerical comparison capabilities within electronic systems.

Feature Summary

• Performs magnitude comparison between two 9-bit binary inputs
• Provides active-high output signals indicating relational states
• Delivers distinct outputs for less than, equal to, and greater than conditions

Applications

• Digital arithmetic logic units
• Binary data sorting circuits
• Numerical control systems

Procurement Notes

Verify the manufacturer designation as National Semiconductor, now part of Texas Instruments, due to corporate acquisitions. Confirm the specific 24-CDIP package dimensions and pinout configuration match system requirements. Ensure compatibility with existing logic voltage levels before integration into designs.

Selection Notes

Select this component when a dedicated 9-bit magnitude comparison function is required with active-high outputs. Consider the 24-CDIP package constraints for board layout and thermal management. Evaluate if the fixed 9-bit width meets the specific data processing needs of the application without requiring additional cascading stages.

Part Context

This component belongs to the National Semiconductor family of digital logic comparators. It serves as a specialized integrated circuit for determining the relationship between two binary values. The device supports standard digital logic operations, providing clear status outputs for downstream processing elements in complex electronic architectures.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence with other 9-bit comparators from current manufacturers if sourcing original parts is difficult.
