Working Principles

The MC74HC374AFG operates based on the principles of D-type flip-flops. It stores and transfers data using clock signals. The data inputs (D0-D7) are latched into their respective flip-flops when a rising edge is detected on the clock input (CP). The stored data can be accessed through the 3-state outputs (Q0-Q7) when the output enable input (OE) is active. The master reset input (MR) allows resetting all flip-flops simultaneously.
