Notes :
1.At output switch point, Vo = 1.4V, Rs = 0 with Vcc
+
from 5V to 30V, and over the full input common-mode range
（
0V
to Vcc
+
-1.5V
）
.
2.The input common-mode voltage of the either input signal voltage should not be allowed to go negative by more than
0.3V. The upper and of the common-mode voltage range is Vcc
+
-1.5V, but either or both inputs can go to +30V
without damage.
3.The response time specified is for a 100mV input step with 5mV overdrive. For larger overdrive signals 300ns can be
obtained.
4.Positive excursions of input voltage may 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 bellow the negative power supply, if used
）
