Working Principles

The SN74AHCT374DGVR is a positive-edge triggered D-type flip-flop. It stores and transfers data based on the clock input signal. When the clock pulse rises from low to high, the data present at the inputs (D0-D7) is latched and transferred to the corresponding outputs (Q0-Q7). The asynchronous master reset input (OE) allows for resetting the flip-flop to a known state. The 3-state outputs enable multiple devices to share a common bus.
