74HC109

The 74HC109 is a high-speed CMOS dual JK flip-flop with asynchronous preset and clear inputs, designed for reliable data storage and flexible signal processing in digital circuits. It provides a compact dual flip-flop configuration that simplifies board layout while offering versatile toggling and storage functions.

• Dual JK flip-flop configuration for flexible storage and toggling capabilities in a single package.
• Wide operating voltage range from 2 V to 6 V for stable operation across common power supplies.
• High switching speed to reduce propagation delays and improve circuit responsiveness.
• Preset and clear inputs for asynchronous control and enhanced design flexibility.
• Low power consumption suitable for energy-conscious and battery-operated applications.

Compared to older logic families, the 74HC109 offers faster switching and lower power requirements consistent with modern CMOS technology. Enhanced input protection and improved noise margins contribute to greater reliability versus legacy TTL devices. The chip’s dual flip-flop structure conserves board space and reduces component count, while robust noise immunity and low propagation delay help maintain signal integrity in a variety of electronic environments.
