TRANSISTOR-TRANSISTOR LOGIC CLIPPING CIRCUIT

摘要

The invention is a combination of a transistor-transistor logic (TTL) gate and a multi-emitter transistor clipping circuit having a different emitter connected to each input of the gate. The multi-emitter transistor is biased so that any signal, reflected by an input of the gate and tending to pull the potential of that input below ground, causes the transistor to conduct and clip the input signal essentially at ground potential.
