is the magnitude of the time difference between the high-to-low and low-to-high propagation delay times at an output.
(2) t
sk(pp)
is the magnitude of the difference in propagation delay times between any specified terminals of two devices when both devices
operate with the same supply voltages, at the same temperature, and have identical packages and test circuits.
