I have hooked datasheeg the following circuit just to test the analog switching capability:. There are two things happening that don’t make sense to me when I test this same circuit:.

It is as if the multiplexer isn’t switching between x0, x1, x2 or x3. For example, it shows that with Vdd at 10v you catasheet at least 7v for a high. Why is there a voltage difference? I started off with both A and B grounded. The DMM measurement reads the value 0. Please let me know if something about this seems incorrect or is I just flat out misinterpreted the use of this chip.

I dont know why, maybe it fried? Your input logic to A,B should use the V1 voltage 12v for a high, not 5v.

The control signals will be inverted from the base input to the collector output connection. Dave Guenther 1 If you need to switch the circuit with only 5v logic you can use an NPN transistor for each input, with a resistor on each collector pulled up to the Vdd level.

Did I hook up this CD Analog Multiplexer correctly? – Electrical Engineering Stack Exchange

That is actually where I would expect it to be. So at 12v Vdd you may need about a 9v minimum.

It never occurred to me that logic high might be relative to Vdd. This resistance adds to the 1 k external resistance and causes the voltage drop you saw. Upon reading the data sheet this chip seems straight forward, but I’m having the hardest time hooking up the CD It is most likely implemented with pairs of back to back MOSFETs as the switches, and they have a daatsheet on resistance of ohms or more.

The analog MUX isn’t equivalent to a short. It seems like it should just be similar to datasueet open wire between the two. Post as a guest Name.
