Delay application circuit is shown in Figure purposes JEC-2 consisting of two. When the input end is logic 0 to 1, the output also immediately end 1 ; but when the input end is
high level 1 transition to low level 0, the output by the delay after it becomes 0, the delay time from 10 F capacitor charging to the trigger level to ask the decision. This circuit provides the delay time is 0.02 to 10 seconds, for the case where the delay time shorter. Change R and C, you can change the delay time. Re value adjustment, you can correct errors.
