Working Principles

The 74HCT574DB,112 is a positive-edge-triggered flip-flop that stores and transfers digital data. It operates based on the clock pulse signal received at the CP pin. When the clock pulse transitions from low to high, the input data is latched and stored in the flip-flop's internal memory. The stored data is then available at the corresponding output pins. The master reset (MR) signal can be used to clear the flip-flop and set all outputs to a known state.
