Working Principles

The 74AHCT74PW,118 is a dual D-type positive-edge-triggered flip-flop. It operates based on the rising edge of the clock signal (CLK). The data inputs (D1 and D2) are latched into the flip-flop when the CLK signal transitions from low to high. The outputs (Q and QN) reflect the input data after the clock transition. The clear (CLR) and preset (PRE) inputs allow for forced output states, overriding the normal operation.
