Pin capacitance is characterized but not tested.
Measured with port in quasi-bidirectional mode.
Measured with port in high-impedance mode.
Port pins source a transition current when used in quasi-bidirectional mode and externally driven from logic 1 to logic 0. This current is
highest when V
= 40 C to +85 C for industrial applications, unless otherwise specified.
