PURPOSE:To obtain a monostable multivibrator circuit which is difficult to generate the malfunction due to a noise signal, by using a flip flop, a charging circuit, an OR gate, a discharging diode, and an initializing circuit. CONSTITUTION:A flip flop circuit 31 having the clear function is initialized by an initializing circuit 36 at a power-on time, and a trigger input is given to an input terminal 32, and one output of the flip flop circuit is given to a charging circuit 34, and the charging output of this charging circuit 34 is made into pulses by a prescribed reference voltage of an OR gate 35, and the flip flop circuit 31 is cleared by this pulse output, and the other output 33 of the flip flop circuit 31 is used as a monostable output pulse. After the charging output reaches once the prescribed reference voltage to clear the flip flop circuit 31, the monostable output pulse is not varied by the noise signal. |
