Abstract
PURPOSE:To obtain a function as a logic circuit at a high speed by providing a 3rd npn bipolar transistor(TR) and connecting a resistor between the base and the emitter of the 3rd npn bipolar TR or a 1st npn bipolar TR. CONSTITUTION:An npn bipolar TR Q3 whose base is connected to a drain of a p-channel MIS field effect TR MP, whose collector is connected to a power terminal E1, whose emitter is connected to a base of the npn bipolar TR Q1 and a resistor R1 connected between the base and emitter of the bipolar TR Q3 are provided on a conventional TR logic circuit. Since the 3rd npn bipolar TR Q3 is turned on when the p-channel MIS field effect TR MP is turned on, the base potential of a 2nd npn bipolar TR is turned on rapidly. Thus, the function as the logic circuit is obtained at a high speed.
