2. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant,
independent of the state of the output, so no loading charge exists on the reference of input lines.
3. The response time specified is for a 100 mV input step with 5 mV overdrive. For larger overdrive signals 300 ns can be
obtained.
4. Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the
common-mode range, the comparator will provide a proper output state. The low input voltage state must not be less than
-0.3 V (or 0.3 V below the negative power supply, if used).
