1. Data based on design simulation only. Not tested in production.
2. The leakage could be higher than the maximum value, if negative current is injected on adjacent pins. Refer to
I/O current injection susceptibility.
3. To sustain a voltage higher than V
4. Pull-up and pull-down resistors are designed with a true resistance in series with a switchable PMOS/NMOS. This
PMOS/NMOS contribution to the series resistance is minimal (~10% order).
