The circuit is designed to meet the DC specifications shown in the above table after thermal equilibrium has been established.
Propagation delay is measured with no attenuating transmission line connected to the input.
Output-to-Output skew is the difference in time between both outputs under identical input transition, temperature and power supply
Part-to-part skew is defined for two parts with identical power supply voltages at the same temperature and no skew at the edges at the
respective inputs.
