Working Principles
CD74HCT574M operates based on the principles of digital logic circuits. When a clock pulse is received, the data present at the input pins is latched onto the flip-flops. This stored data is then available at the output pins until the next clock pulse arrives. The output enable pin controls whether the stored data is accessible at the outputs or not. The master reset pin resets all flip-flops to their initial state when activated.
