Working Principles

The CY74FCT821BTSOC is an 8-bit D-type flip-flop with 3-state outputs. It operates based on the positive edge of the clock pulse (CP) input. When the clock pulse rises, the data inputs (D0-D7) are latched and stored in the flip-flop. The stored data can then be accessed through the corresponding outputs (Q0-Q3). The output enable (OE) pin controls whether the outputs are active or in a high-impedance state.
