General description
The 74LVC821A is a 10-bit D-type flip-flop featuring separate D-type inputs for each flip-flop and 3-state outputs for bus-oriented applications. A clock input (pin CP) and an output enable input (pin OE) are common to all flip-flops. The ten flip-flops store the state of their individual D-inputs that meet the set-up and hold times requirements on the LOW-to-HIGH CP transition. When pin OE is LOW, the contents of the ten flip-flops are available at the outputs.
