1) Number of outputs defined as "n". Measured with "n-1" outputs switching from HIGH to LOW or LOW to HIGH. The remaining output is
measured in the LOW state.
2) Number of outputs defined as "n". Measured with "n-1" outputs switching from HIGH to LOW or LOW to HIGH. The remaining output is
measured in the HIGH state.
3) Parameters guaranteed by design.

1) Skew is defined as the absolute value of the difference between the actual propagation delay for any two outputs of the same device switch-
ing in the same direction, either HIGH or LOW (tOSLH = | tPLHm - tPLHn|, tOSHL = | tPHLm - tPHLn|)
2) Parameter guaranteed by design
