100331QC

Overview

The Fairchild Semiconductor 100331QC is a digital logic integrated circuit containing three D-type, edge-triggered master/slave flip-flops. It features true and complement outputs for each stage, a Common Clock Pin (CPC) architecture, and Master Set (MS) functionality. The device is housed in a 28-pin PLCC package.

Feature Summary

• Contains three independent D-type master/slave flip-flops with edge triggering
• Provides both true and complement output signals for each flip-flop
• Includes Master Set capability for asynchronous initialization

Applications

• Parallel data storage registers
• Shift register configurations
• Digital state machine control circuits

Procurement Notes

Verify the manufacturer origin as Fairchild Semiconductor, noting that the entity has been acquired by ON Semiconductor. Confirm the specific PLCC-28 package type and ensure the component matches the original Fairchild specifications rather than generic equivalents. Check for lead times associated with legacy or discontinued part numbers from the current supplier base.

Selection Notes

Select this component when a compact solution for triple D-type flip-flops is required within a single package. The common clock pin design simplifies timing synchronization across multiple stages. Ensure the application voltage levels are compatible with standard TTL/CMOS logic families supported by this device family.

Part Context

The 100331 series belongs to Fairchild's standard logic portfolio, designed for general-purpose digital applications. As a legacy product from Fairchild Semiconductor, it represents established technology now managed under ON Semiconductor's distribution channels following corporate acquisition.
