Notes:
8. High-frequency AC-parameters are guaranteed by design and characterization.
9. Output-to-output skew is measured between two different outputs under identical input transitions.
10. Part-to-part skew is defined for two parts with identical power supply voltages at the same temperature and with no skew of the edges at the
respective inputs
