Working Principles
The SN74HCT374PWRE4 operates based on the principles of D-type flip-flops. When the clock pulse (CP) is triggered, the input data (D0-D7) is transferred to the corresponding flip-flop outputs (Q0-Q7). The output enable (OE) pin controls whether the outputs are active or in a high-impedance state. The master reset (MR) pin resets all flip-flops to a known state when activated.
