Working Principles

The 74ACT574SC operates based on the principles of flip-flops. It utilizes positive-edge-triggered D-type flip-flops to store and transfer data. When the latch enable (LE) signal is active, the input data is latched and stored. On the rising edge of the clock input (CLK), the stored data is transferred to the output pins (Q0-Q7). The output enable (OE) signal controls the visibility of the output data.
