RPull

Pullup or pulldown resistor

For pullup: VIN = VSS

Input capacitance

VIN = VSS or VCC

(1)

The leakage current is measured with VSS or VCC applied to the corresponding pins, unless otherwise noted.

(2)

The leakage of the digital port pins is measured individually. The port pin is selected for input and the pullup/pulldown resistor is

disabled.

The maximum total current, I(OHmax) and I(OLmax), for all outputs combined should not exceed ±48 mA to hold the maximum voltage drop

specified.

(1)

A resistive divider with two 50-k

Ω resistors between VCC and VSS is used as load. The output is connected to the center tap of the

divider.
