Functional Features

  • Dual D-type flip-flops allow independent storage and manipulation of binary data.
  • Positive-edge-triggered clock input ensures synchronized operation.
  • Clear and preset inputs provide control over the flip-flop states.
  • Complement outputs provide inverted versions of the main outputs.

Advantages and Disadvantages

Advantages: - Versatile and widely used in digital circuits. - Compact design with two flip-flops in a single package. - Easy to integrate into larger systems. - Reliable performance within specified temperature and voltage ranges.

Disadvantages: - Limited functionality compared to more advanced flip-flop types. - Not suitable for high-speed applications due to relatively slow propagation delay. - Requires external components for proper operation.

Working Principles

The DM7473N operates based on the principles of positive-edge-triggered flip-flops. When the clock input receives a rising edge, the data present at the D inputs is transferred to the corresponding Q outputs. The clear and preset inputs allow for resetting or setting the flip-flop states, respectively. The complement outputs provide inverted versions of the main outputs.
