Thanks a lot for all your help on the 555 issue.

Here is another question:

Does anyone know of a book that talks about the CD4098 multivibrator?
THis is an RCA chip, and I believe its counterpart is Motorola's 
MC14528 which lists the  MC14538  as preferred "for new development".
ANyhow, I got the cd4098

This is a dual multivibrator. What I really need to know is
the formulas to figure out the timing and how long it will stay "down"
and then how long it will be "UP". Also what type of input is it 
waiting on, etc.    I read somewhere that the resistor that goes on the
RC circuit on this chip should be >= 5K ohm.  They did not explain
why. The publication did NOT say that timing would be erratic if I
placed a lower value resistor.



Any info send direct to me:

Thanks.
