Functional Features

• Dual flip-flop with independent data inputs and outputs
• Positive-edge-triggered operation
• Asynchronous clear input (CLR) to reset both flip-flops
• Common clock input (CLK) for both flip-flops
• Individual data inputs (D1 and D2) for each flip-flop
• Individual outputs (Q1 and Q2) for each flip-flop

Advantages and Disadvantages

Advantages: - Wide supply voltage range allows compatibility with various systems - Small package size enables space-saving designs - High-speed operation for efficient data processing

Disadvantages: - Limited number of flip-flops in a single package - Not suitable for applications requiring negative-edge triggering

Working Principles

The SN74LVC2G74DCUR is a dual positive-edge-triggered D-type flip-flop. It operates based on the rising edge of the clock signal (CLK). When the CLK input transitions from low to high, the data at the D1 and D2 inputs are latched into the Q1 and Q2 outputs, respectively. The asynchronous clear input (CLR) can be used to reset both flip-flops to a known state.

Detailed Application Field Plans
