ABSTRACT:
A TTL gate circuit is provided with an additional transistor biased by the base of the input transistor. This additional transistor supplies current to the phase splitter emitter load, to thereby bias the phase splitter transistor off until the input voltage is high enough to turn both the phase splitter transistor and the output transistor on. The result is a substantially square voltage transfer characteristic.
