Note 7: This is the current sourced when a high output is shorted to ground. Only one output at a time should be shorted.
Note 8: Skew is defined as the difference in propagation delays between complementary outputs at the crossing point.
Note 9: Output disable time is the delay from the control input being switched to the output transistors turning off. The actual disable times are less than indicated
due to the delay added by the RC time constant of the load.
