See Typical Performance Characteristics and Applications Information
sections. The LT1160 = 1/2 LT1162.
Note 4: See Timing Diagram. Gate rise times are measured from 2V to 10V
and fall times are measured from 10V to 2V. Delay times are measured
from the input transition to when the gate voltage has risen to 2V or
decreased to 10V.
