54ACT109WRQMLV

Overview

The 54ACT109WRQMLV is a dual J-K flip-flop from the ACT series, manufactured by National Semiconductor. It features two positive-edge-triggered functions with complementary outputs. The device is constructed using CMOS technology and is housed in a CDFP16 package. It is designed for high-speed digital applications requiring reliable state storage and sequential logic control within military or aerospace environments.

Feature Summary

• Dual J-K flip-flop configuration with positive edge triggering
• Complementary output availability for each function
• ACT series CMOS construction for high-speed performance

Applications

• Military-grade sequential logic circuits
• Aerospace data storage systems
• High-reliability digital counters

Procurement Notes

Verify the specific QMLV qualification status and manufacturer documentation to ensure compliance with required military standards. Confirm package integrity and date codes upon receipt. Cross-reference part numbers carefully as National Semiconductor assets are managed by Texas Instruments.

Selection Notes

Select this component when dual independent J-K flip-flops with complementary outputs are required in a ruggedized environment. Ensure system voltage levels match the ACT series specifications. Consider the CDFP16 package constraints for board layout and thermal management in enclosed military assemblies.

Part Context

This part belongs to the 54ACT family of high-speed CMOS logic devices originally developed by National Semiconductor. The QMLV suffix indicates qualification under specific military reliability standards. The 54ACT series provides performance comparable to TTL but with lower power consumption and wider voltage tolerance suitable for harsh environments.

Replacement Considerations

Check for direct equivalents in the 54ACT series from Texas Instruments or other qualified vendors offering QMLV-qualified dual J-K flip-flops in CDFP16 packages. Verify pinout compatibility and electrical parameter alignment before substitution.
