[sdiy] Another "which chip" question

[Scott Stites]

Hi Larry,

I use the 7555, which has a very low current drain and is very kind to the PS rails.  I learned about these from Rene Schmitz, who uses them in his VCO3 for just that reason.  Jameco has them with a very good price.   Mouser has them, too.  Dual variant is the 7556.

Cheers,
Scott

I'm planning some simple clock circuits with 555 and the dual version 556
chips.  I seem to recall some discussion here about one version of the 555
being a rather nasty player.  Someone care to recommend a particular one of
the many variations of these puppies?  Or, something I should stay away
from?  I'm using +/- 15 VDC supply.  So, most any Vcc is OK.

Thanks
