A feature of some digital electronic devices which allows a connector (pin) to either act as a normal output, driving a signal onto a line, or to be "tri stated" - set to a high-impedance ("high Z") condition. This allows other outputs to drive signals onto the line. Often the same connector also functions as an input when its output circuitry is tri stated.Tri-state outputs are typically used for the connection of several digital circuits to a shared bus onto which any one of them may output data for the others to input.
