PURPOSE:To make easy circuit integration for the circuit including the latch circiut and to avoid malfunction, by constituting the set circuit with transistors and diodes and resistors without using capacitors. CONSTITUTION:The set circuit is constituted with the DC power supply 1, power supply switch 2, and integrated circuit element 3 consisting of the power supply control circuit 6 controlled with the initial condition set circuit 4, latch circuit 5. With this consitution, the circuit 4 is provided with the transistors Tr1 to Tr6, diodes D1 to D3 and resistors R1 to R3, and power supply is fed to the circuit 5 with Tr3, and power supply is fed to the trigger pulse generation circuit to make the circuit at initial condition from Tr4. Next, the circuit 15 is provided with Tr7 and Tr8, where flip flop operation is made. Further, the circuit 6 consists of Tr9 to Tr11 and resistors R5 and R6, and the supply and interruption of power supply is made with the output of the circuit 5. Thus, the set of initial condition is ensured. |
