1.
2. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant,
3. Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the
4. The response time specified is for a 100 mV input step with 5 mV overdrive.
5. Maximum values are guaranteed by design and evaluation.
