Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is in-
tended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the electrical characteristics.
Note 2:
Human body model, 1.5 k
in series with 100 pF. The output pins of the two comparators (pin 1 and pin 7) have an ESD tolerance of 1.5 kV. All other pins
have an ESD tolerance of 2 kV.
Note 3:
Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in exceeding the
maximum allowed junction temperature of 150C. Output currents in excess of
±
30 mA over long term may adversely affect reliability.
Note 4:

inlcudes the probe and jig capacitance. The rise time, fall time and propagation delays are measured with a 2V input step.
Note 10:
Input offset voltage Average Drift is calculated by dividing the accelerated operating life drift average by the equivalent operational time. The input offset
voltage average drift represents the input offset voltage change at worst-case input conditions.
