Functional Features

• Dual D-type positive-edge-triggered flip-flop with clear and preset inputs.
• Can store and transfer data based on the clock signal.
• Provides complementary outputs for each flip-flop.

Advantages and Disadvantages

Advantages: - High-speed operation - Wide supply voltage range - Low power consumption - Small package size

Disadvantages: - Limited number of flip-flops in a single package - Not suitable for applications requiring a large number of flip-flops

Working Principles

The SN74AC74PWRG4 operates as a dual D-type positive-edge-triggered flip-flop. It stores and transfers data based on the rising edge of the clock signal. The clear and preset inputs allow for resetting or setting the flip-flop to a specific state. The complementary outputs provide both the normal and inverted versions of the stored data.

Detailed Application Field Plans

The SN74AC74PWRG4 is commonly used in various digital systems, including:

1. Sequential logic circuits
2. Data storage and transfer systems
3. Microcontrollers and microprocessors
4. Communication systems
5. Control systems
