with Vcc from 5V to 30V and over the full input common-mode range(0V
to Vcc 1.5V).
2.The direction of the input current is out of the IC due to the PN P input stage. This current is essentially constant,
independent of the state of the output, so no loading charge exists on the reference or input lines.
3.The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than
0.3V.The upper end of the common-mode voltage range is Vcc+ -1.5V,but either or both inputs can go to +30V
without damage.
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 –0.3V(or 0.3V below the negative power supply, if used).
5.The response time specified is for a 100mV input step with 5mV overdrive. For larger overdrive signals 300ns can
be obtained.
