Notes : 2. Atoutput switchpoint,VO#1.4V,R
S=0ΩwithVCC+from 5Vto 30V and over thefullinputcommon-mode range (0V
toVCC+1.5V).
3. The direction of the input current is out of the IC dueto the PNP input stage. This current is essentially constant,
independent of the state of the output, so no loading charge exists on the reference or input lines.
4. The input common-mode voltage ofeither inputsignal voltage should not beallowed togo negative bymore than
0.3V. The upper end of the common-mode voltage range is VCC+–1.5V, but either or both inputs can go to +30V
without damage.
5. The response time specified is for a 100mV input step with 5mV overdrive.
6. Positive excursions of input voltage may exceed the power supply level.
As long asthe other voltage remains within thecommon-mode range thecomparator willprovide a proper output
state. Thelowinput voltagestate must not be lessthan –0.3V (or0.3V belowthenegative power supply,ifused).
7. Maximum values are guaranteed by design.
