Functional Features

• Positive-edge-triggered flip-flop: The SN74LV174APWRE4 stores and transfers data on the rising edge of the clock pulse.
• Low-voltage operation: It can operate at a supply voltage as low as 1.65V, making it suitable for low-power applications.
• Quad flip-flop: The IC contains four independent flip-flops, allowing for multiple data storage and transfer operations.

Advantages and Disadvantages

Advantages: - Low-voltage operation enables energy-efficient designs. - Compact TSSOP package saves board space. - High-speed operation with a maximum frequency of 30MHz.

Disadvantages: - Limited number of flip-flops compared to other ICs. - Not suitable for high-voltage applications.

Working Principles

The SN74LV174APWRE4 operates based on the positive-edge-triggered flip-flop principle. When a rising edge is detected on the clock input (CP), the data present on the D input is transferred and stored in the flip-flop. The stored data is then available on the Q output. The complementary output Q' provides the inverse of the stored data.
