Stresses beyond 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 beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

Note 1:
All devices are production tested at T
A
= +25°C. Limits over temperature are guaranteed by design.
Note 2:
When V
CC
falls below the UVLO threshold, the outputs deassert (OUT goes low). When V
CC
falls below 1.2V, the output
state cannot be determined.
Note 3:
During the initial power-up, V
CC
must exceed 2.25V for at least 0.5ms before OUT can go high.
