Working Principles

The SN74AHCT74PW is a dual D-type positive-edge-triggered flip-flop. It stores and transfers binary data based on the rising edge of the clock signal. The data input (D) is latched into the flip-flop when the clock input (CLK) transitions from LOW to HIGH. The complementary outputs (Q and Q̅) reflect the stored data, with Q being the inverse of Q̅. The asynchronous clear (CLR) and preset (PR) inputs allow for immediate initialization of the flip-flop's state.
