Notes:
13. Minimum limits are specified but not tested on Propagation Delays.
14. See test circuit and waveform.
15. See “Parameter Measurement Information” in the General Information section.
16. These conditions are specified but not tested.
17. These limits are specified but not tested.
18. Skew between any two outputs of the same package switching in the same direction. This parameter is ensured by design.
