Notes:
17. Minimum limits are specified but not tested on Propagation Delays.
18. See “Parameter Measurement Information” in the General Information section.
19. This parameter is specified but not tested.
20. Skew between any two outputs of the same package switching in the same direction. This parameter is ensured by design.
