The trend from long ago is towards LSI for complete systems, and FPLA type
products for specialty high volume solutions.
For low volumns and one-of, I'd be looking at a PIC. Be aware that's more
programming than wiring!

Subject: [TowerTalk] Radio Button IC?
Hello,
Is there a single IC that will provide the same functions as the old car
radio buttons?
Building a direction selector for an eight direction receiving antenna
system and would like to use push buttons to select the direction. Desire
is to have the first button pushed to lock out the other buttons should two
or more buttons be push at nearly the same time. Something similar to the
way the station selector buttons worked on old car radios.
An arrangement using several discrete ICs has been worked out, but would be
nice to have a single IC do the same thing. I've looked through several
parts supplier catalogs, but haven't found an IC that seems to do the
functions as the old car radio buttons.
73,
Mike, K4GMH
