Functional Description
The VCX16721 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.
