Propagation delay is measured with no attenuating transmission line connected to the input.
Input-to-Input skew is the difference in time between both inputs and the output for the same temperature, voltage and transition.
Output-to-Output skew is the difference in time between both outputs under identical input transition, temperature and power supply
