Abstract

PURPOSE:To stabilize the operation of a digital information processing device, by selectively cutting the connection wiring between the emitter and the load resistor of a corresponding transistor when an emitter follower circuit is selectively made ineffective, and selectively adding the connection wiring between the collector and the emitter or between the base and the emitter. CONSTITUTION:Connection wirings are provided between the emitters of transistors T5 and T6 and load resistors R5 and R6. Said connection wirings are cut at marks Xs in the Figure. An emitter follower circuit comprising the transistors T5 and T6 is selectively made ineffective. Therefore, a collector capacitor CC5 is equivalently coupled between the base and the collector of the transistor T5. An emitter capacitor Ce5 is equivalently coupled between the base and the emitter of the transistor T5. The same pattern is provided for the transistor T6. Thus the transmission delay time of a bipolar logic circuit becomes approximately constant regardless of the number of the effective emitter follower circuits. Therefore, the operation of a digital information processing device including the bipolar logic circuit is stabilized.
