Turn-on Delay and Rise Times
(at 80% of IO, max; TA = 25 °C):
Case 1: On/Off Input Is Set for Logic High and then Input
Power Is Applied (delay from point at which VI = VI, min until
VO = 10% of VO, set).
Case 2: Input Power Is Applied for at Least One Second, and
Then the On/Off Input Is Set to Logic High (delay from point at
which Von/off = 0.9 V until VO = 10% of VO, set).
