Functional Features

The 74ACTQ273SC is a D-type flip-flop with a master reset function. It can store and latch data based on the clock input signal. The master reset input allows for clearing the stored data when necessary.

Advantages

• High-speed operation enables efficient data processing.
• Low power consumption helps conserve energy in electronic systems.
• Wide operating voltage range provides flexibility in various applications.
• Schmitt-trigger inputs ensure noise immunity, enhancing reliability.
