eight edge-triggered flip-flops with individual D-type inputs and TRI-STATE true outputs The buffered clock and buffered Output Enable are common to all flip-flops The eight flip-flops will store the state of their individual D inputs that meet the setup and hold time requirements on the LOW-to-HIGH Clock (CP) transition With the Output Enable (OE) LOW the contents of the eight flipflops are available at the outputs When the OE is HIGH the outputs go to the high impedance state Operation of the OE input does not affected the state of the flip-flops Truth Table Inputs Dn H L X CP L L X OE
