tsk(o) is the skew between specified outputs of a single device with all driving inputs connected together and the outputs switching in the same
direction while driving identical specified loads.
§tsk(pp) is the magnitude of the different in propagation delay times between any specified terminals of two devices when both devices operate
with the same supply voltages, same temperature, and have identical packages and test circuits.
