Functional Features

• Dual D-Type Flip-Flop: The SN74LVC74ADG4 consists of two independent D-type flip-flops, allowing for the storage and transfer of binary data.
• Positive-Edge Triggered: The flip-flops are triggered on the rising edge of the clock signal, ensuring synchronized data transfer.
• Low-Voltage Operation: This IC operates at low voltage levels, making it suitable for battery-powered devices and other low-power applications.
• CMOS Logic: The use of CMOS technology provides high noise immunity and low power consumption.

Advantages and Disadvantages

Advantages: - Low-voltage operation allows for compatibility with a wide range of systems. - CMOS logic ensures efficient power usage and high noise immunity. - Dual flip-flop configuration provides flexibility in circuit design.

Disadvantages: - Limited to positive-edge triggering, which may not be suitable for all applications. - Availability in only SOIC package limits options for certain form factors.

Working Principles

The SN74LVC74ADG4 operates based on the principles of D-type flip-flops. When the clock input (CP) receives a rising edge, the data present at the D1 and D2 inputs is transferred to the respective Q1 and Q2 outputs. The CLR input can be used to clear the flip-flop outputs to a known state when activated.
