Note 1. 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 out-
put state. The low input voltage state must not be less than –0.3V (or 0.3V below the the
magnitude of the negative power supply, if used).
Note 7. The response time specified is for a 100mV input step with 5mV overdrive. For larger over-
drive signals 300ns can be obtained.
