    • 1. What does ECL stand for?

    • Options
    • A. It stands for electron-coupled logic; all of the devices used within the gates are N-type transistors.
    • B. It stands for emitter-coupled logic; all of the inputs are coupled into the device through the emitters of the input transistors.
    • C. It stands for emitter-coupled logic; all of the emitters of the input transistors are connected together and each transistor functions as an emitter follower.
    • D. It stands for energy-coupled logic; the input energy is amplified by the input transistors and allows the device to deliver higher output currents.
