Working Principles

The CY74FCT821BTSOCTG4 is a flip-flop integrated circuit that stores and retrieves digital data. It operates based on the clock signal provided at the CLK input. When the clock pulse arrives, the data present at the D0-D7 inputs is latched and stored in the corresponding Q0-Q7 outputs. The G (Gate) input controls whether the clock signal is enabled or disabled, allowing for selective operation of the flip-flop. The MR (Master Reset) input resets all flip-flops to a known state when activated.
