Electrical Characteristics
Table 3.
1.
2. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant,
3. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more
4. Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains
5. The response time specified is for a 100mV input step with 5mV overdrive.
6. Maximum values are guaranteed by design & evaluation.

independent of the state of the output, so no loading charge exists on the reference of input lines
than 0.3V. The upper end of the common-mode voltage range is V
+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 below the negative power supply, if used)
