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 OutputEnable 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.
