100353QCX

Overview

The Fairchild Semiconductor 100353QCX is an octal D-type flip-flop register featuring eight edge-triggered, master/slave flip-flops. It provides individual data inputs (Dn) and true outputs (Qn) with a common clock input. The device is housed in a 28-LCC (J-Lead) package and supports positive edge triggering for reliable data storage. It operates within a maximum junction temperature of 125 °C, ensuring stability in standard logic applications requiring parallel data retention.

Feature Summary

• Contains eight independent D-type master/slave flip-flops for parallel data handling
• Utilizes positive edge triggering mechanism for synchronous operation
• Provides true output states corresponding to input data levels

Applications

• Parallel data storage registers
• Shift register configurations
• Timing control circuits

Procurement Notes

Verify the specific suffix 'QCX' against the manufacturer's official documentation to confirm package type and material specifications. Ensure compatibility with existing board layouts for the 28-LCC J-Lead footprint. Cross-reference electrical ratings with system requirements before integration.

Selection Notes

Select this component when an octal register with positive edge triggering is required. The LCC package suits surface-mount designs needing compact footprints. Confirm voltage levels and speed requirements align with the 100K series characteristics. Evaluate thermal management needs given the 125 °C operating limit.

Part Context

This part belongs to the Fairchild 100K series of low-power Schottky TTL logic devices. The 100353 variant specifically addresses applications requiring multiple synchronized storage elements. It represents a standard solution for digital systems needing parallel-to-serial or serial-to-parallel conversion capabilities within legacy or mixed-signal environments.

Replacement Considerations

Check for direct equivalents from other manufacturers offering identical pinouts and logic functions. Verify that substitute parts maintain the same master/slave architecture and edge-triggering behavior. Ensure package dimensions match the 28-LCC specification to avoid mechanical interference.
