• Dual D-type positive-edge-triggered flip-flop
• Non-inverting outputs
• Asynchronous reset input (CD) for clearing the flip-flop
• Common clock input (CP) for both flip-flops
• Individual data inputs (D1 and D2) for each flip-flop
• Outputs (Q1, Q2) provide the stored data at the outputs

Advantages and Disadvantages

Advantages: - Low-voltage operation allows compatibility with various systems - High-speed operation with low propagation delay - Compact TSSOP-14 package saves board space - Asynchronous reset input provides flexibility in clearing the flip-flop

Disadvantages: - Limited output drive capability compared to some other ICs - Requires careful handling due to its small package size

Working Principles

The 74ALVC74BQ,115 is a dual D-type positive-edge-triggered flip-flop. It stores and transfers data based on the rising edge of the clock signal (CP). The individual data inputs (D1 and D2) are sampled when the clock rises, and the stored data is available at the outputs (Q1 and Q2). The asynchronous reset input (CD) can be used to clear the flip-flop, forcing the outputs to a known state.
