On data sheets and such what is the current that flows from an input pin referenced to ground called? On a level shifter input I measured 1.6v but im not sure why an input would output a voltage, unless that's a leakage of a high impedance output. From what I got its the IOZ current shown in datasheets but I'm not sure. Any info would be appreciated, thanks.
You don't give a link to the datasheet for the device in question.
That one, its for 3.3v arduino due to 5v 8086 but I'm just curious what piece of info on there defines this behavior. Say if I set direction to A -> B the A pins still measure 1.6v when floating
I believe the IOZ being +-1 UA would mean that it will still sink and allow draw of 1uA. Would that charge an input to 1.6v?
That's a worst case, typical leakages are more like nA I'd have thought.
DMMs are usually 10Mohm inputs, so 100nA gives 1V reading. Or you can
use a current reading on the DMM directly.
Hi, what application do you have that needs to consider the current going to an input that is in the uA range.?
