Functional Features

The SN74AS374NSR is a D-type positive-edge-triggered flip-flop. It has the following functional features:

  • High-speed operation, making it suitable for applications requiring quick data storage and retrieval.
  • Low-power consumption, ensuring efficient use of energy.
  • Clear input (CLR) allows for resetting the flip-flop to a known state.
  • Data inputs (D0-D7) enable the storage of binary information.
  • Clock input (CLK) triggers the flip-flop on the rising edge of the clock signal.

Advantages and Disadvantages

Advantages: - High-speed operation enables rapid data processing. - Low-power consumption reduces energy usage. - Clear input allows for easy reset of the flip-flop. - Versatile application in various digital systems.

Disadvantages: - Limited number of flip-flops per IC package. - Requires an external clock signal for proper operation.

Working Principles

The SN74AS374NSR operates based on the positive-edge-triggered D-type flip-flop principle. When a rising edge is detected on the clock input (CLK), the data present at the D-inputs (D0-D7) is transferred to the corresponding Q-outputs (Q0-Q7). The outputs retain their states until the next rising edge occurs.
