<p>An emitter coupled logic circuit includes variable impedance circuit (20) which is connected to at least one of two output terminals of the ECL circuit for variably providing an impedance connected to the one output terminal. An impedance to be provided when both the levels of the two outputs are at a high-level is set to be smaller than an impedance to be provided when at least one of the two outputs is at a low-level.</p> |
