IPC: H03K19/08
Filed: 1990-10-23
Abstract: PURPOSE:To avoid production of a large reverse bias voltage between an emitter and a base caused-by a rapid decrease in a base level by including an active discharge circuit to a base charge discharging circuit of a bipolar transistor(TR). CONSTITUTION:N-channel MOS TRs M5, M6 are connected to an NPN bipolar TR Q1 so as to discharge a charge of a base of the TR Q1, and a gate of an N-channel MOS TR M8 connecting to a source of the TR M6 is connected to a power supply terminal Tv and the TR M8 is always conductive. When a level of an output terminal To, that is, an emitter level Vo of the TR Q1 is switched from an H level to an L level, a base charge of the TR Q1 is forcibly discharged as a drain current in the saturation region of the TR M8. Thus, it is avoided that a large reverse bias voltage is applied to the emitter-base junction of the TR Q1.
