Working Principles

CD74ACT374M operates based on the principles of digital logic. When the clock pulse input (CP) is triggered, the data inputs (D0-D7) are latched and stored in the flip-flop. The stored data can then be outputted through the corresponding output pins (Q0-Q7) when the output enable (OE) signal is active. The clock enable function allows control over when the data is transferred.
