Note 1: For inputs >12V, add a 1 kΩ resistor in series with the input. See “Typical Characteristics” 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.
