WebAny monostable multivibrator that has an external RC circuit for timing will operate on the same basic principle. The capacitor in an RC circuit will take a set amount of time, referred to as the ‘time constant,’ to charge up to 63.2% of … WebNov 22, 2009 · Hi all. I am using a CD4528 Dual Monostable Multivibrator and when it is first powered on, it starts the 1st clock. I want to get it to start up and NOT start the clock. It is being used as a 2 stage timer (4 stages shown in schem.) where the 1st timer must end (go low) before the 2nd timer starts. hard calf muscle pain
