Functional Description
The 74ALVC16721 contains twenty D-type flip-flops with
3-STATE standard outputs. The twenty flip-flops will store
the state of their individual D-type inputs that meet the
setup and hold time requirements on the LOW-HIGH Clock
(CLK) transition, when the Clock-Enable (CE) is LOW. The
3-STATE standard outputs are controlled by the Output
Enable (OE). When OE is HIGH, the standard outputs are
in high impedance mode but this does not interfere with
entering new data into the flip-flops.
