1.
At output switch point, V
O
=1.4V, RS=0
Ω
with V+ from 5V
DC
to 30 V
DC
; and over the full input common-mode range (0V
DC
to
V+-1.5V
DC
).
2. The direction of the input current is out of the IC due to the PNP input stage. This current essentially constant, independent of
the state of the output so no loading change exists on the reference or input lines.
3. The input common-mode voltage or either input voltage signal should not be allowed to go negative by more than 0.3V. The
upper end of the common-mode voltage range is V+-1.5V at 25°C, but either or both inputs can go to +30V without damage,
independent of the magnitude of V+.
4. The response time specified is for a 100mV input step with 5 mV overdrive. For larger overdrive signals 300 ns can be
obtained.
5. Positive excursions of input voltage may exceed the power 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
DC
(or
0.3V
DC
below the magnitude of the negative power supply, if used) (at 25°C).
