PROBLEM TO BE SOLVED: To generate the identical output pulse width in all input transitions and to generate the delay of only one gate in a circuit by generating an output pulse, at the time of detecting the transition of one node from among several input nodes by using a single delay pass. SOLUTION: A precharging means is provided with plural field effect transistor(FET) devices P0 to P2, which have respective gates connected to respective transition inputs. A 1st charging device FETP 3 charges an output node 25 to a high level. A 2nd charging device FETN3 discharges the output node 25 to a low level. A single delay means is connected between plural transition inputs and the 1st and 2nd charging devices FETP3, FETM3 to turn off the FETP3 and turn on the FETN3. Switching means FETN0 to FETN2 are controlled by plural transition inputs and connected between the output node 25 and the device FETN3, to disconnect the device FETN3 from the output node 25. |
