Re: 555 timer...
Original poster: David Speck <Dave@xxxxxxxxxxxxxxxx>
Simple approach is to put a NPN inverting transistor on the output
and use it that way. I think there is an inherent feature of the way
that the 555 works internally that makes it hard to do what you want directly.
There are, however, lots of web sites that have all kinds of exotic
555 circuits if you want to go for a more elegant solution.

This is kinda off topic but, can someone please help me with
this...I am trying to get a 555 timer rectangle pulse (Basic
Astable) to stay low longer then it is high...Is this possible? I
have achieved near equal (square) but never longer low then it is
high?? Thanks for any help.
