2. Values based on characterization results, and not tested in production.
3. Hysteresis voltage between Schmitt trigger switching levels. Based on characterization results, not tested.
4. With a minimum of 100 mV.
5. Leakage could be higher than max. if negative current is injected on adjacent pins.
6. Pull-up and pull-down resistors are designed with a true resistance in series with a switchable
