General: Input pulse widths greater than the Nominal
value (XX in ns from P/N TTLPD-XX) of the module,
will propagate with delay of (XX + 5ns) ± 5% or 2 ns,
whichever is greater. Output pulse width will follow
the input width ± 7% or 4 ns, whichever is greater.
Input pulse widths less than the Nominal value will be
suppressed.
