Notes:
1. Unless otherwise specified, typical data are based on TA=25°C and VDD=5V.
2. Data based on characterization results, not tested in production.
3. Hysteresis voltage between Schmitt trigger switching levels. Based on characterization results, not tested.
4. The Rpull-up equivalent resistor is based on a resistive transistor. This data is based on characterization results, not
tested in production.
