Note 1: For inputs >12V, add a 1 k⦠resistor in series with the input. See âTypical Characteristicsâ graph for input
current.
2: Switching times are ensured by design.
3: For operation below 7V, pin 3 (LOCK DIS) should be tied to ground to disable the lockout and start-up cir-
cuit, otherwise, pin 3 must be left floating.
