100331QIX

Overview

The Fairchild Semiconductor 100331QIX is a triple D-type flip-flop integrated circuit designed for digital logic applications. It features three independent edge-triggered master/slave flip-flops with both true and complement outputs, operating on a common clock signal. The device includes Master Set (MS) and Master Clear (MC) inputs for asynchronous control of the flip-flop states. Manufactured by Fairchild Semiconductor, this component is housed in a 28-pin PLCC surface-mount package, suitable for high-density PCB layouts. It supports standard logic voltage levels and offers reliable performance for data storage and transfer functions in electronic systems.

Feature Summary

• Triple D-type configuration with master/slave architecture
• Common clock input for synchronized operation
• Asynchronous Master Set and Master Clear controls
• True and complement output availability per element

Applications

• Digital data storage registers
• Shift register circuits
• State machine implementations
• Parallel-to-serial conversion modules

Procurement Notes

Verify the specific manufacturer source, as Fairchild Semiconductor's semiconductor division has undergone corporate restructuring and brand transitions to onsemi. Ensure the part number matches the original Fairchild datasheet specifications rather than potential successor variants. Confirm RoHS compliance status and lead-free markings on the physical component. Check for any obsolescence notices or lifecycle status updates from authorized distributors before finalizing procurement plans.

Selection Notes

Select this component when a compact solution for triple D-type latching is required in surface-mount designs. The 28-pin PLCC package offers a balance between pin count and board space efficiency. Consider the common clock architecture if synchronous data handling across multiple bits is necessary. Evaluate the asynchronous reset/set capabilities against system power-up requirements. Ensure compatibility with existing logic voltage levels and interface timing constraints in the target application design.

Part Context

This component belongs to the family of digital logic integrated circuits manufactured by Fairchild Semiconductor. It serves as a fundamental building block for sequential logic circuits, providing reliable data retention and transfer capabilities. The triple configuration allows for efficient implementation of multi-bit storage elements within a single package, reducing component count and simplifying board layout compared to using individual single flip-flop devices.

Replacement Considerations

Check for direct cross-reference equivalents from onsemi, which acquired Fairchild's semiconductor business. Verify pinout compatibility and logical functionality against alternative triple D-type flip-flops from other manufacturers such as Texas Instruments or NXP. Ensure that any substitute maintains the same package type and electrical characteristics to avoid redesign efforts.
