Functional Features

  • Dual D-Type Positive-Edge-Triggered Flip-Flop: The SN74ACT74PWRE4 consists of two independent D-type flip-flops with positive-edge triggering. It allows data to be stored and transferred synchronously with the clock signal.
  • Clear Function: The active LOW clear input (CLR) allows the user to reset the flip-flops to a known state.
  • Wide Supply Voltage Range: The IC operates within a supply voltage range of 2 V to 6 V, making it suitable for various digital systems.
  • High-Speed Operation: The positive-edge triggering ensures fast and reliable data storage and transfer.

Advantages and Disadvantages

Advantages: - Dual flip-flop configuration provides flexibility in circuit design. - Wide supply voltage range allows compatibility with different systems. - High-speed operation enables efficient data handling.

Disadvantages: - Limited number of flip-flops per IC package. - Not suitable for applications requiring negative-edge triggering.

Working Principles

The SN74ACT74PWRE4 operates based on the principles of positive-edge-triggered flip-flops. When the clock input (CLK) transitions from LOW to HIGH, the data present at the D1 and D2 inputs is transferred to the Q1 and Q2 outputs, respectively. The outputs hold their states until the next clock transition occurs. The clear input (CLR) can be used to reset the flip-flops to a known state when activated.

Detailed Application Field Plans

The SN74ACT74PWRE4 is commonly used in various digital systems where data storage and transfer are required. Some application fields include:

  1. Microcontrollers: Used for storing and transferring data between different components of a microcontroller.
  2. Communication Systems: Enables data synchronization and transfer in communication protocols.
  3. Data Processing Units: Facilitates data handling and manipulation in processing units.
  4. Memory Systems: Used for address decoding and data storage in memory systems.
