Working Principles

CD74HCT163E operates based on synchronous binary counting principles. The clock input (CP) triggers the counter to increment its value by one on each rising edge of the clock signal. The count enable (CEP) and parallel load (PL) inputs control the counter's behavior, allowing preset values to be loaded or enabling/disabling counting. The carry output (CO) indicates when the counter reaches its maximum value.
