Abstract
A CBiCMOS transmission gate in which the sources of a CMOS transistor pair are connected to an input and the drains are connected to the bases of a complementary bipolar transistor pair. The bipolar transistor pair is serially connected between a plus voltage potential and ground whereby a logic one applied to the input is transmitted through the PMOS transistor to the base of an NPN transistor which applies the plus voltage to an output terminal, and a logic zero applied to the input is transmitted to the NMOS transistor to the base of a PNP transistor to apply ground to the output terminal.
