PURPOSE:To achieve an output pulse with longer time width, by shaping the waveform at an output pulse trailing edge, through the connection of a differntiating circuit at an output side of a monostable multivibrator (MMV) and inputting an output of the differentiating circuit to a clear terminal of the MMV. CONSTITUTION:When an input pulse A is applied to an input terminal 5, an MMV is operated to output an output QC at an output terminal 6. This output QC is branched and applied to an NAND gate 9 via inverters 7 and 8. Since one output Q' is applied to the NAND gate 9, the output of the NAND gate 9 clears a monostable multivibrator with the waveform differentiating the output pulse of the MMV and shapes the trailing edge of the output pulse of the MMV to make the trailing steep. |
