Working Principles

The 74ACT563SC operates based on latch/flip-flop principles. When the latch enable (LE) pin is activated, the data inputs (D0-D7) are latched and stored internally. The stored data can then be accessed through the corresponding output pins (Q0-Q7). The clock input (CLK) synchronizes the latching process, allowing for precise control over data storage and retrieval.
