I have a technical question in regards to the ADuC7026. The digital inputs does not state the allowable sinking current. I have seen 1.6mA stated for the digital outputs so since these pins are Digital I/O pins I am assuming that the current sinking max is 1.6mA. I wanted to know what would be the effect of sinking 20mA through the input line? Will this cause issues? What is the nominal sinking current that is recommended?
