A semiconductor logic circuit apparatus includes a plurality of logic circuits each including complementary field effect transistors, and a plurality bipolar transistors associated with the respective ones of the logic circuits. When any one of the outputs of the logic circuits becomes high, an associated bipolar transistor becomes conductive to cause an output terminal of the apparatus to be charged from a voltage supply. With all the outputs of the logic circuits being low, all of the bipolar transistors are non-conductive, and a current supply coupled between the output terminal and ground dicharges charge on the output terminal.
