Functional Features

The 74LVX74SJ is a dual D-type positive-edge-triggered flip-flop with clear and preset functionality. It is designed to store and transfer data in digital systems. The positive-edge-triggered feature ensures that the flip-flop captures the input data on the rising edge of the clock signal. The clear and preset inputs allow for synchronous resetting and setting of the flip-flop outputs.

Advantages and Disadvantages

Advantages: - Dual flip-flop configuration allows for efficient use of space in integrated circuits. - Positive-edge triggering ensures reliable data capture. - Clear and preset inputs provide flexibility in controlling the flip-flop outputs.

Disadvantages: - Limited supply voltage range (2.0V to 5.5V). - Relatively low output current capability (-4.0mA to 4.0mA).

Working Principles

The 74LVX74SJ operates based on the principles of digital logic gates. The flip-flop stores and transfers binary data using internal latches. The clock signal triggers the transfer of data from the input to the output. The clear and preset inputs allow for synchronous resetting and setting of the flip-flop outputs, respectively.
