tsk(o) is the skew between outputs of a single device with all driving inputs connected together and the outputs switching in the same
direction while driving identical loads.
(3)
tsk(pp) is the magnitude of the difference in propagation delay times between any terminals of different devices switching in the same
direction while operating at identical supply voltages, temperature, input signals and loads.
