Note 2: All units are production tested at T

= +25°C. Specifications over temperature are guaranteed by design and characterization.
Note 3: All voltages are referenced to ground, unless otherwise noted.
Note 4: See the Boost Current section for more information.
Note 5: Not production tested. Guaranteed by design
Note 6: V
CC
is an auxiliary supply input. When V
CC
is powered from an external 3V to 5.5V supply, the propagation delay is
reduced and the output changes from a current souce to a CMOS output. When using power from IN to power the device,
connect V
CC
to GND (V
CC
= 0V).
Note 7: Thermal shutdown protection is only enabled when V
CC
is present. Thermal shutdown does not occur when V
CC
= 0V.
