Notes:

(1)

+

from 5 V to 30 V, and over the full input common-mode range

(2)

The direction of the input current is from 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)

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 provides 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).

(4)

The response time specified is for a 100 mV input step with 5 mV overdrive.

(5)

Maximum values are guaranteed by design and evaluation.
