DEFINITION OF TERMS:
SETUP TIME (ts) — is defined as the minimum time required
for the correct logic level to be present at the logic input prior
to the clock transition from LOW-to-HIGH in order to be recog-
nized and transferred to the outputs.
HOLD TIME (th) — is defined as the minimum time following
the clock transition from LOW-to-HIGH that the logic level
must be maintained at the input in order to ensure continued
recognition. A negative hold time indicates that the correct
logic level may be released prior to the clock transition from
LOW-to-HIGH and still be recognized.
RECOVERY TIME (trec) — is defined as the minimum time
required between the end of the PL pulse and the clock
transition from LOW-to-HIGH in order to recognize and
transfer loaded Data to the Q outputs.
