Working Principles

The 74ABT821PW,112 is a D-type flip-flop that stores data on the rising edge of the clock signal. When the clock input (CP) transitions from low to high, the data present at the D0-D9 inputs is transferred to the corresponding Q0-Q9 outputs. The output enable (OE) pin controls the state of the outputs. When OE is low, the outputs are active; when OE is high, the outputs are in a high-impedance state.
