1) Worst case package.
2) Max number of outputs defined as (n). Data inputs are driven 0V to 3.3V, (n-1) outputs switching and one output at GND.
3) Max number of data inputs (n) switching. (n-1) switching 0V to 3.3V. Inputs under test switching: 3.3V to threshold (VILD), 0V to threshold
(VIHD), f=1MHz.

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
