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.
Note 10: CPD determines the no load dynamic power consumption, PD = CPD V2CC f + ICC VCC, and the no load dynamic current consumption, IS = CPD VCC f +
ICC.
Note 11: ESD Rating: HBM (1.5 kΩ, 100 pF)
Inputs ≥ 1500V
Outputs ≥ 1000V
