In order to couple high-frequency input signals to a transmission line with the aid of a GTL output amplifier, the GTL output amplifier provides not only a pull-down stage (MN1) but also a pull-up transistor circuit (MP1, MN2). When there is an input signal (E) of the first value, the output (A) is set at a first potential with the aid of the pull-down stage (MN1) and with the aid of the pull-up transistor circuit (MP1, MN2) the output is set at a second potential on the transition of the input signal from the first to the second value. The pull-up transistor circuit is then blocked and the potential at the output is determined by the potential on the line. When the input signal once again assumes the first value, the pull-down circuit is switched on again and applies the first potential again to the output. |
