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