Re: Bad design?

Is this a bad design:

I have 5 connections (switches on a X10 mini home controller) that
either
need to get shorted with pin A or pin B.

I am planning on using two CD4066 bilateral switches
(http://www.fairchildsemi.com/ds/CD/CD4066BC.pdf).

Each of the 5 inputs would have TWO connections connected to it, one
from
pin A and one from pin B (outputs of two of the 'spare' switches). As
long
as I am careful not to have both switch A and switch B enabled at the
same
time is this a bad design?



Not necessarily. It's common practice (bustranceivers for instance) to tie
outputs together and make sure the hardware always keeps at least all but
one in tristate. So if you have it in your own hand, it will do. It's
still
the hardware - controlled by your program but nevertheless - that enables
at
most of the switches.
