Abstract
A transistor circuit of the invention comprises a current mirror circuit including input-side bipolar transistors and output-side bipolar transistors, an on-off control circuit including MOS transistors for on-off controlling of the base current of the output-side bipolar transistors, and MOS transistors for rendering the output-side bipolar transistors to securely turn off. The MOS transistors are normally connected between the bases of the output-side transistors and a ground terminal.
