Tri state is 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.

The property has 3 states it can be in.
For instance a check box in VB6 can be Checked, UnChecked or Grayed.
