Honored ContributorMax V output pin in a disconnected mode on logic 1
I'm using Max V dev kit for basic logic gate design. No clocking or anything. Logic part works fine. On logic 1 / high I would like the output pin to be floating / disconnected. Right now it pr...

electrically, the output does not achieve perfect floating (infinite impedance) but only a large impedance. Thus, if nothing else is driving the line, you'll still see some kind of voltage on the line, which will depend on the output driver design and internal states.
