Charles,

I did not misquote you and I did stick to the facts.

Quote: "The CD4067 (16 input multiplexer analog input IC) CMOS integrated circuit is capable of handling 0-10VDC input signal with the proper sit [sic] up. Below is a circuit which shows how to hook up one."
Then you show a schematic intended for 0-5V signals.

Fact: For the 4067 to handle 0-10V inputs, its Vdd must be 10.5V at the very least, 12V is prefereable.
Fact: At 12V Vdd, the control inputs have a Vih(min) of around 9V.
Fact: A microcontroller supplied with 5V will not deliver the required Vih.
Fact: Merely changing Vdd from 5V to 12V in the schematic you linked to is not going to work. More importantly: It will suffer from the same problem the original poster has, namely that the incorrect voltage to the control input will make both P- and N-channel transistors inside the device turn on, effectively shorting the supply voltage.

For independend, verifiable references, please read the appropriate device datasheets. For example:
Philips HEF FAMILY SPECIFICATIONS
TI CD4067 datasheet

You're welcome,
