2. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially
3. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more
4. The response time specified is for a 100mV input step with 5mV overdrive.
5. Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains
6. Maximum values are guaranteed by design.

than 0.3V. The upper end of the common-mode voltage range is V
to +30V without damage.
within the common-mode range, the comparator will provide a proper output state. The low input voltage state
must not be less than –0.3V (or 0.3V bellow the negative power supply, if used)
