Web29 apr. 2010 · 2 Answers. "Tristate" means a state of high impedance. A pin can either pull to 0 V (sinking current, generally), pull to 5 V (sourcing current, generally), or become high impedance, like an input. The idea is that if a pin is in high impedance state, it can be pulled to high or low by an external device without much current flow.
