Notes:
(1)At the output switch point, Vo ≈ 1.4 V, RS = 0 Ω with (VCC+) from 5 V to 30 V, and over the full input common-mode range
(0 V to (VCC+) – 1.5 V).
(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 there is no load charge on the reference of input lines.
(3)Positive excursions of the 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)
(4)The response time specified is for a 100 mV input step with 5 mV overdrive. For larger overdrive signals, 300 ns can be
obtained.
