Note
1: For inputs >12V, add a 1kΩ 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 circuit, otherwise, pin 3 must be left
floating.
