Working Principles

The SN74HC574DBR is an octal D-type edge-triggered flip-flop. It operates based on the clock pulse input (CP) and stores data from the data inputs (D0-D7) when a rising edge is detected on the clock signal. The stored data is then available at the corresponding output pins (Q0-Q7). The output enable (OE) pin allows for enabling or disabling the outputs, making it suitable for bus-oriented applications.
