<p>A transistor circuit has a first series circuit of first (R4) and second (R5) resistors coupled between a power source line (Vcc) and a circuit ground line (GND). A second series circuit of third (R6) and fourth (R7) resistors is connected in parallel to the first series circuit. A first transistor (01) is coupled at its collector-emitter path between the junction of third and fourth resistors and the circuit ground line. The first transistor is on-off controlled by a potential appearing at the junction of the first and second resistors. A second transistor (Q2) is coupled at its collector-emitter path between an output terminal (OUT) of the reset circuit and the circuit ground line. The second transistor is on-off controlled by a potential appearing at the junction of the third and fourth resistors. The ratio (R4/R5) of the resistance value of first resistor (R4) to that of second resistor (R5) is larger than the ratio (R6/R7) of the resistance value of third resistor (R6) to that of fourth resistor (R7).</p> |
