CHARACTERISTICS
† Stresses above those listed under "Absolute Maximum
Ratings" may cause permanent damage to the device. These
are stress ratings only and functional operation of the device
at these or any other conditions above those indicated in the
operation sections of the specifications is not implied.
Exposure to Absolute Maximum Rating conditions for
extended periods may affect device reliability.

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
circuit, otherwise, pin 3
must
be left floating.
