Output skew (tsk(o)) is the magnitude of the time delay difference between the outputs of a single device with all of the inputs connected together.
§
Part-to-part skew (tsk(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 input signals, the same supply voltages, at the same temperature, and have identical packages and test
circuits.
