Advantages and Disadvantages

Advantages: - High-speed operation allows for efficient data transfer. - Compatibility with TTL logic levels ensures easy integration into existing systems. - Dual flip-flop configuration provides flexibility in data storage and transfer.

Disadvantages: - Limited voltage range (2V to 6V) may restrict its use in certain applications. - Power dissipation of 500mW may require additional cooling measures in high-power circuits.

Working Principles

The CD74HCT74M96 operates based on the principles of positive-edge-triggered D-type flip-flops. When the clock input (CLK) receives a rising edge, the data input (D1 or D2) is captured and stored in the corresponding flip-flop. The stored data is then available at the respective output pins (Q1, Q1', Q2, Q2') until the next clock pulse triggers a new data capture.
