Patent JP-S62104311-A (JP)
Title: Switch circuit
Inventor: IDA SHIZUO
IPC: H03K17/60
Filed: 1985-10-31
Abstract: PURPOSE:To form a low input current type switch circuit which deals with a low input voltage by constituting a PNP differential amplifying circuit at an input stage by using four PNP transistors (TR) and using it for the transmission of an input voltage, and connecting a current mirror circuit to the differential amplifying circuit when switch control is performed. CONSTITUTION:When a switch circuit control terminal 28 is at 'H', a current flows through the PNP mirror circuit 40 and the differential amplifying circuit 30 operates, so that a voltage which is an high as the voltage (Vin) at an input terminal 6 is developed at an output terminal 7. When the control terminal 28 is at 'L', on the other hand, no current flows through the PNP mirror circuit 40, so the differential amplifying circuit 30 does not operate and the input voltage (Vin) is not outputted. The input voltage, therefore, becomes extremely low and the influence of the load is reduced. Further, the input is transmitted by the PNP differential amplifying circuit composed of TRs 8-11, so the input is transmitted even with a low input voltage including '0'V.
