1. Hysteresis voltage between Schmitt trigger switching levels.
2. When the current limitation is not possible, the V
3. Leakage could be higher than max. if negative current is injected on adjacent pins.
4. Configuration not recommended, all unused pins must be kept at a fixed voltage: using the output mode of
