  • Patent number: 4975600
    Abstract: An output driver circuit for reducing output terminal ringing in integrated circuits has a plurality of pull-down transistors each having first, second and third terminals. A plurality of voltage setting devices each are connected in series to the second terminal of one of the pull-down transistors. An input is connected to the common third terminals of the plurality of pull-down transistors, and an output pull-up circuit is connected between the output of the circuit and the first terminals of the plurality of pull-down transistors. Multiple output driver circuits, each having an input delayed with respect to the others, can be connected together with a common output.
