constraints the propagation delay can be described as:

where T
accounts for nonuniformity introduced by temperature and
voltage variability, whereas the delay dispersion parameter
takes into consideration input slew rate and input voltage
overdrive variability. Thus a modified propagation delay can
be approximated to account for the effects of input conditions
that differ from those under which the parts where tested. For
example, an application may specify an ECL input with a
slew rate of 0.25 V/NS, an overdrive of 17 mV and a
temperature of 25°C, the delay dispersion parameter would
be 100 ps. The modified propagation delay would be
