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
(*) Voltage range is 3.3V ± 0.3V
