Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2:
This specification guarantees that both the high and low trip points
of the comparator fall within the 1.2V to 1.3V range.
Note 3:
The output voltage waveform will exhibit a sawtooth shape due to
the comparator hysteresis. The output voltage on the fixed-output versions
will always be within the specified range.
Note 4:
100k resistor connected between a 5V source and the AO pin.
