Functional Description
The 74ALVC16821 contains twenty D-type flip-flops with
3-STATE standard outputs. The device is byte controlled
with each byte functioning identically, but independent of
each other. Control pins can be shorted together to obtain
full 20-bit operation. The following description applies to
each byte. 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-to-HIGH Clock (CLK) transition.
The 3-STATE standard outputs are controlled by the Out-
put Enable (OE
n
) input. When OE
n
is HIGH, the standard
outputs are in the high impedance mode but this does not
interfere with entering new data into the flip-flops.
