Datasheet

Note 2: All devices are production tested at T
A
= +25°C. Limits over temperature are guaranteed by design.
Note 3: When V
CC
falls below the UVLO threshold, the outputs will deassert (OUT goes low, OUT goes high). When V
CC
falls
below 1.2V, the out cannot be determined.
Note 4: Guaranteed by design.
Note 5: During the initial power-up, V
CC
must exceed 1.5V for at least 2ms before the output is guaranteed to be in the correct
state.
(V
CC
= 1.5V to 5.5V, T
A
= -40°C to +125°C, unless otherwise specified. Typical values are at V
CC
= 3.3V and T
A
= +25°C, unless
otherwise noted.) (Note 2)
