Working Principles

The 74FCT2574CTSOCTG4 operates based on the principles of positive-edge-triggered flip-flops. When a rising edge is detected at the clock input (CP), the data present at the D-type inputs (D0-D7) is latched and stored in the corresponding flip-flops. The stored data can then be accessed through the output pins (Q0-Q6) when the output enable (OE) signal is active.
