Conditions
For inputs >12V, add a 1 kΩ resistor in series with the input. See “Typical Characteristics” graph for input
current.
Switching times are ensured by design.
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.
