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
3) Typical values at VCCA = 5.0V, VCCB = 3.3V
(*) Voltage range is 3.0V ± 0.3V
