ABSTRACT:
A feedback circuit is provided between the output and the input of a lower transistor amplifier of a push-pull amplifier driver output stage to inhibit power supply transients as the amplifier output stage transitions rapidly from a low to high output state. Additionally, if the push-pull output stage is incorporated within a three state gate or the like, which gate shares a common bus with other like three state gates, the feedback circuit inhibits loading of the bus whenever the three state gate is operated in a three state mode or is powered down as the other gates are active and are rapidly transitioned between low and high output states. The feedback circuit provides a low impedance path at the input of the lower transistor amplifier of the push-pull driver output stage to shunt transient currents harmlessly away from the base thereof to prevent the transient currents from turning on the lower transistor amplifier.
