The q denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C.
VIN = 3V, 0°C ≤ TA ≤ 70°C unless otherwise noted.
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 1.20V to 1.30V 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 A0 pin.
The q denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C.VIN = 3V, Military or Commercial Version
