Inputs Output Enable TRI-STATE Input Clock Input TRI-STATE Outputs Functional Description The ’F821 consists of ten D-type edge-triggered flip-flops This device has TRI-STATE true outputs for bus systems organized in a broadside pinning The buffered Clock (CP) and buffered Output Enable (OE) are common to all flipflops The flip-flops will store the state of their individual D inputs that meet the setup and hold times requirements on the LOW-to-HIGH CP transition With the OE LOW the content of the flip-flops 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 affect the state of the flip-flops Function Table Inputs OE H H H H L L L L CP H L L L L L H L D X X L H L H X X Internal Q NC NC H L H L NC NC
