Abstract
There is provided emitter coupled logic (ECL) circuitry comprising a differential amplifier circuit for receiving an input signal and a reference potential Vbb, and for causing an output circuit to make a transition to its high state by charging a parasitic capacitor which is parasitic in the output circuit, and make a transition to its low state by discharging a charge stored in the parasitic capacitor to a potential Vtt by way of a load resister, according to whether or not the level of the input signal is larger than the reference potential Vbb, and a discharge switching circuit which can switch to its conductive state in response to a control signal applied thereto so that the charge stored in the parasitic capacitor is also discharged to the negative potential Vee by way of the discharge switching circuit.
