Working Principles

The CD74HCT174MG4 operates based on the principles of D-type flip-flops. It stores and transfers data using positive-edge-triggered clock inputs (CP) and asynchronous master reset (MR) inputs. When the clock input receives a rising edge, the data present at the D input is transferred to the corresponding Q output. The MR input allows for resetting all flip-flops to a known state when activated.
