ABSTRACT:
A semiconductor integrated bipolar flip-flop circuit prevents or suppresses erroneous operation arising from a current induced by external noise and flowing through a parasitic capacitance associated with a p-type diffused resistor. The semiconductor integrated circuit includes bipolar transistors that are directly involved with set and reset operations of the flip-flop circuit having bases connected to a two-stage inverter including bipolar transistors so that the bases of the bipolar transistors involved in setting and resetting are not connected directly to a p-type diffused resistor.
