CD74ACT109M

Overview

The CD74ACT109M is a dual J-K positive-edge-triggered flip-flop manufactured by Harris Corporation. It contains two independent JK-type elements within a single package, designed for high-speed CMOS logic applications. The device features complementary outputs and includes dedicated preset and clear functions to control the state of each flip-flop independently. It operates within a standard voltage range typical for ACT series components and is housed in a 16-SOIC package with a width of 3.90mm. This component serves as a fundamental building block for sequential logic circuits requiring reliable data storage and transfer capabilities.

Feature Summary

• Dual independent J-K flip-flops with positive-edge triggering
• Complementary output configuration for versatile logic interfacing
• Integrated preset and clear control inputs for direct state management

Applications

• Sequential logic circuit design
• Data storage and transfer systems
• Digital counter implementations

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels, as this part is listed as obsolete. Confirm package integrity and pin alignment against the 16-SOIC specification before integration. Check for cross-reference availability from Texas Instruments if original Harris stock is unavailable. Ensure handling procedures comply with ESD standards for CMOS devices.

Selection Notes

Select this component when dual independent JK flip-flops are required in a compact SOIC package. Consider the positive-edge trigger characteristic for timing-sensitive designs. Evaluate the complementary output type for driving subsequent logic stages directly. Verify compatibility with existing system voltage levels and signal integrity requirements before finalizing the design choice.

Part Context

The CD74ACT109M belongs to the 74ACT series of high-speed CMOS logic devices produced by Harris Corporation. It is functionally equivalent to other dual JK flip-flop variants within the same logic family. The device represents a specific implementation of sequential logic technology, offering reliability for digital applications where precise edge-triggered operation is necessary.

Replacement Considerations

CD74ACT109M is identified as an alternative substitute option where inventory availability or cost considerations are primary factors. Cross-reference with Texas Instruments equivalents may be necessary due to the obsolete status of the Harris Corporation part.
