22.1.3. Interfacing Port I/O to 5V Logic
All Port I/O configured for digital, open-drain operation are capable of interfacing to digital logic operating at
a supply voltage higher than VDD and less than 5.25 V. An external pullup resistor to the higher supply
voltage is typically required for most systems.
Important Note: In a multi-voltage interface, the external pullup resistor should be sized to allow a current
of at least 150 µA to flow into the Port pin when the supply voltage is between (VDD + 0.6 V) and (VDD +
1.0 V). Once the Port pin voltage increases beyond this range, the current flowing into the Port pin is mini-
mal.
