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 recognized and transferred to the outputs.
HOLD TIME (t
h
) — 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.
