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 recog-
nition. 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 re-
quired between the end of the reset pulse and the clock transi-
tion from LOW to HIGH in order to recognize and transfer
HIGH Data to the Q outputs.
