  • High speed logic level converter
    Patent number: 3986045
    Abstract: A two branch circuit for converting dual complementary signals characterizing emitter coupled logic to a single signal characterizing transitor-transistor logic. A two branch circuit supplies translation between ECL input signals, referenced to a voltage supply and TTL output signals, referenced to ground, using a current summing node receiving current from both branches and connected to a TTL output driver. A first circuit branch includes a feedback loop which generates a reference current summed with the current in the second branch.
