Hi,
Thanks for your reply. I salute you all.
What I could conclude in 'Off' condition is:
As pin 15 of 4017 is directly connected to the base of an NPN transistor (inside of the IC), the cap then easily discharges through base-emitor and any other components forming a closed circuit?
Well, I've just inspired to the cap of a DC adaptor. The cap is still fully loaded despite the AC feeder is off.
Back to the last topic of 4017 reset, does the RC circuit of 100n and 100K ensure autoreset at anytime power on?
Thank you.
