3. T he dir ection of t he input curre nt is o ut of the IC d ue to the PN P input stage . Thi s curr ent i s essentially const ant , independent of the stat e of the out put, so no loading charge exists on the re ference or input l i nes.

4. T he input common-mode vo ltage of eit her inp ut signal vol t age should not be allow ed to go negative by more than

0.3V . The upper end of the common- mode voltage r ange is V damage.

5. T he r esponse ti m e specified is for a 100m V input step w ith 5mV overdri ve. For lar ger overdr i ve signals 300ns can be obtai ne d.

6. P ositive excursions of i nput volt age may ex ceed the pow er supply level. As l ong as the other vol t age remains wit hin the comm on- mode range t he com parator willprovi de a pr oper outpu t state. The low input volt age state must not be less than –0.3V (or 0.3V below the negat i ve power supply, if used).
