100131FCQL

Overview

The F100131FCQL is a D Flip-Flop component manufactured by National Semiconductor, belonging to the ECL100K logic family. It features three functional units within a single package, utilizing a master-slave triggering mechanism for data synchronization. The device is housed in a ceramic CQFP24 surface-mount package with 24 terminals. It operates with a supply voltage of -4.5 V and draws a maximum supply current of 149 mA. The propagation delay at nominal supply is specified as 2.2 ns. The component supports an operating temperature range from -55 °C to 85 °C and has a moisture sensitivity level of 2A.

Feature Summary

• Integrates three independent D flip-flops in a single ceramic package
• Utilizes ECL100K technology for high-speed master-slave triggering
• Designed for surface-mount assembly via QFF flatpack housing

Applications

• High-speed digital signal processing systems
• ECL-based logic circuit designs
• Master-slave data storage applications

Procurement Notes

Verify the manufacturer origin carefully, as Fairchild Semiconductor acquired National Semiconductor's logic business. Confirm the specific suffix 'QL' matches the required ceramic package variant. Check RoHS compliance status, as older ECL parts may not meet current environmental standards. Ensure the supplier provides valid traceability documentation for legacy components.

Selection Notes

Select this component when designing circuits requiring multiple synchronized D-type registers within a high-speed ECL environment. The ceramic package offers superior thermal stability compared to plastic variants. Consider the -4.5 V power requirement and ensure the system design accommodates the associated negative voltage generation and termination resistors typical for ECL logic families.

Part Context

This part belongs to the ECL100K series, a high-performance emitter-coupled logic family known for speed. The F100131 specifically provides triple D flip-flops. The 'F' indicates the logic function, '100K' denotes the family, 'C' signifies the ceramic package, 'Q' refers to the flatpack form factor, and 'L' typically indicates lead-free or specific terminal finish variations depending on the era of production.

Replacement Considerations

Direct pin-compatible replacements are limited due to the specific ECL100K characteristics. Verify if other manufacturers offer equivalent ECL triple D flip-flops in ceramic packages. Cross-reference timing parameters such as the 2.2 ns propagation delay to ensure compatibility with existing clock speeds.
