Curt -
OK. Guess you have to look and see what the circuit is! The standard CMOS chips are CD4016, which
is a Quad Analog Switch. Motorola's version is a MC14016, which is why the 'extra' 1 at the
beginning. I seem to recall now that Motorola DID have a series of 4000 chips, much like the 10000
series MCL. The TR-7 uses about a half dozen of the MC14016 (CD4016) switches.
Thanks for the clarification, ya gotta look at the diagram to be sure.

Well..that may be true but here is the motorola datasheet for the MC4016
It is indeed a Mod N divide by counter.. My app was in a HP counter board.

No, it's a 4016 / 14016, same thing. It's a quad analog switch used in the TR-7 as well.
Motorola just put the '1' in front of the CMOS number.
The 4066 / 14066 is the same thing too. Easy to find.

I think he's talking about a 4016P..it is a dip package divide by N chip. I think I found one
for a counter I was repairing. I'll check in the morning to see. I remember having a devil of
a time finding one.

If it's a 14 pin DIP package the MC14016 is available from Mouser, Digi-Key and others. It's
just a CMOS Quad Analog switch.
Google MC14016BCP is the plastic DIP, the MC14016BCPG is the wide temperature
version.

Looking for a MC4016P for a UV3 divider board. This is an obsolete part. Any
sources?
