  • Patent number: 4912344
    Abstract: A novel output stage is provided for producing a TTL output signal in response to the differential output signals from an ECL switch. The output stage includes a translator portion to shift the levels of the complementary signals produced by the ECL switch to the appropriate levels for use in driving a TTL output stage, a phase splitter circuit which is driven by the level shifted complementary output signals from the ECL stage and a single output lead. The currents through the level shifting transistors and resistors are controlled by a single current reference generator. The output signals from the translator circuit have voltage levels substantially independent of variations in the power supply voltage.
