Working Principles

The 74HC574D-Q100,118 operates based on the principles of flip-flop circuits. When the latch enable (LE) input is high, the data inputs (D0-D7) are latched into the flip-flops on the rising edge of the clock (CLK) signal. The latched data is then available at the corresponding output pins (Q0-Q7). The output enable (OE) input controls whether the data outputs are active or in a high-impedance state.
