Chn ne555n pdf

Stand-alone problem monostable I bet this hcn has been answered before and sorry for that, but all previous titles are like ” help” and i cannot find the answer to that specific problem, i ask for your n555n I am using monostable timers for a project, and all of them have output constantly high 1 when the input is constantly high 1which I think is against the expected responses. If I change the input to 0 then the output lowers to 0 after the expected time and remains so.


Mar 21, 2. Apr 2, 9, 1, A trigger will cause it to switch and after the cbn constant it will revert back to it’s stable state Recheck ur wiring.

Mar 21, 3. Feb 20, 2, 1, I suppose when you say “it remains so,” you expect it to go high again on-off-on-etc.

That would be astable operation which requires this circuit: I hope this helps Der Strom. Mar 21, 4. Thanks for welcoming, I’ve been reading around for a while but never bothered registering till now! Hm, I’ve messed up my initial description, and i see i cannot edit it, I got it wrong.

So here’s more clear: I need monostable operation, like LowLowLow The wiring seems fine. Mar 21, 5.

ne555n Dec 20, 10, 1, Pin 2 must become high again or the timer will never time out. When the timer times out the output goes low.


Mar 21, 6. Jul 1, be555n, You can solve your problem by edge triggering the Mar 21, 7. Most datasheets for the show how to edge trigger it. Mar 22, 8.

Mar 24, 21, 2, Mar 22, 9. Mar 22, Ns555n exact details are explained in the theory of operation in the link I gave. Apr 3, Thank you very much guys, edge triggering works and it’s easy if you understand it. Posted by Erbser in forum: Embedded Systems and Microcontrollers.
