Em3rgent0rdr (talk | contribs) →Digital circuits: the way it was written can be misread to sound like push-pull. Also I think this is "An" alternative, not "The" alternative. I can imagine other forms of amplified output, like optical output or magnetic output or some other forms of energy even. So "an" is safer. |

Line 33:
A disadvantage of simple push–pull outputs is that two or more of them cannot be connected together, because if one tried to pull while another tried to push, the transistors could be damaged. To avoid this restriction, some push–pull outputs have a third state in which both transistors are switched off. In this state, the output is said to be ''floating'' (or, to use a proprietary term, [[Three-state logic|''tri-stated'']]).
