It never occurred to me that logic high might be relative to Vdd. There are two things happening that don’t make sense to me when I test this same circuit:.

That is actually where I would expect it to be. This resistance adds to the 1 k external resistance and causes the voltage drop you saw.

It is most likely implemented with pairs of back to back MOSFETs as the switches, and they have a significant on resistance of ohms or more. For example, it shows that with Vdd at 10v you need at least 7v for a high. Why is there a voltage difference?

Email Datasueet, but never shown. I started off with both A and B grounded. Dave Guenther 1 Nedd 4, 6 It is as if the multiplexer isn’t switching between x0, x1, x2 or x3. I have hooked up the following circuit just to test the analog switching capability:.
Please let me know if something about this seems incorrect or is I just flat out misinterpreted the use of this chip.

While R1 reads 0. I have hooked up the following circuit just to test the analog switching capability: The analog MUX isn’t equivalent to a short.
The control signals will be inverted from the base input to the collector output connection. So at 12v Vdd you may need about a 9v minimum.
