Note 3: Dynamic supply current is higher due to the gate charge
being delivered at the switching frequency. See typical performance
characteristics and applications information.
Note 4: Gate rise times are measured from 2V to 10V, delay times are
measured from the input transition to when the gate voltage has decreased
to 10V, and fall times are measured from 10V to 2V.
