[sdiy] Using the VEE pin on a 405x Multiplexer

Hey all,

I'm trying to understand how to use VEE (Pin 7) on a 4053 Multiplexer.

My understanding is that I can apply a negative voltage bias to this pin which will allow an AC signal to pass through (I'm hoping for approx. 10V PP @ +/-5V) - all while powering it with +12V @ VDD Pin 16.

Can anyone confirm a) if this understanding is right, b) what the maximum negative voltage is (is -12V OK?) that I can apply to VEE and c) is it just one in, one out or is there some equation balance between VDD & VEE.

The data sheet for the HCF4053 shows it getting 0V, -5V, -7.5V and -10V but the text talks about -13.5V (with VDD @ 5V)

Help. Thanks much.
