DEFINITIONS 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.
