ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS
(V
IN
= +2.7V to +13.2V, T
A
= -40癈 to +85癈, unless otherwise noted. Typical values are at V
IN
= +5V and T
A
= +25癈.) (Note 2)
Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress rating s only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specificatio   ns is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
Note 1: ON can be pulled below ground. Limiting the current to 2mA ensures that this pin is never lower than about -0.8V.
