Working Principles

The SN74LVC74APWRE4 is a dual D-type flip-flop that operates on positive-edge triggering. When the clock input (CLK) transitions from LOW to HIGH, the data at the D1 and D2 inputs are latched into their respective flip-flops. The outputs (Q1 and Q2) reflect the state of the inputs at the last clock transition.

The clear (CLR) and preset (PRE) inputs allow for synchronous reset functionality. When the clear input is activated (LOW), both flip-flops are reset to a known state. Conversely, when the preset input is activated (LOW), the flip-flops are set to a predefined state.

Detailed Application Field Plans

The SN74LVC74APWRE4 is commonly used in various digital systems and applications, including:

1. Microcontrollers and microprocessors
2. Data storage devices
3. Communication systems
