Functional Features

• Dual D-type positive-edge-triggered flip-flop
• Direct clear input for synchronous clearing
• High-speed operation with low power consumption
• Compatible with TTL (Transistor-Transistor Logic) input/output levels
• Balanced propagation delays

Advantages and Disadvantages

Advantages: - High-speed operation allows for efficient data processing - Low power consumption reduces energy usage - Compatible with TTL, enabling easy integration into existing systems - Synchronous clearing provides precise control over the flip-flop state

Disadvantages: - Limited supply voltage range may restrict certain applications - Requires careful consideration of clock pulse timing to avoid data corruption

Working Principles

The 74AHCT74D,112 is a dual D-type flip-flop that operates on positive-edge-triggered clock pulses. It stores data at the D input and transfers it to the Q output on each rising edge of the clock pulse. The complementary output, Q̅, is also available. The flip-flop can be cleared synchronously using the CLR input, which sets both outputs to a low logic level.
