WebIn digital circuits, a high impedance (also known as hi-Z, tri-stated, or floating) output is not being driven to any defined logic level by the output circuit. The signal is neither driven to a logical high nor low level; this third condition leads to the description "tri-stated". [1] Such a signal can be seen as an open circuit (or "floating ... Webthe signal trace exceeds this trace-length/speed criterion, then termination should be used. For example, PCB tracks for high-speed logic with rise/fall time of 5 ns should be terminated in their characteristic impedance if the track length is equal to or greater than 10 inches (where measured length includes meanders).
