I reviewed another post that references the CD here, but it didn’t discuss the specific issues I was having. It is as if the multiplexer isn’t switching between x0, x1, x2 or x3. I started off with both A and B grounded.
Did I hook up this CD Analog Multiplexer correctly? – Electrical Engineering Stack Exchange
I have hooked up the following circuit just to test the analog switching capability:. The analog MUX isn’t equivalent to a short. Why is there a voltage difference? Please let me know if something about this seems incorrect or is I just flat out misinterpreted the use of this chip.
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.
Post as a guest Name. That is actually where I would expect it to be. For dataeheet, it shows that with Vdd at 10v you need at least 7v for a high.
View cd4052be datasheet:
Your input logic to A,B should use the V1 voltage 12v for a high, not 5v. Also see the switching limitations listed datassheet jms. The R2, R3 and R4 all read 0v.
Home Questions Tags Users Unanswered. So at 12v Vdd you may need about a 9v minimum.

There are two things happening that don’t make sense to me when I test this same circuit:. Upon reading the data sheet this chip seems straight forward, but I’m having the hardest time hooking up the CD It seems like it should just be similar to an open wire between the two.

I dont know why, maybe it fried? Here is a link to the datasheet. Sign up or log in Sign up using Google.
Nedd 4, 6 I have hooked up 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: The DMM measurement reads the value 0. 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.
Then send 5v signals into the base of each transistor with a series base resistorand the emitter is connected to GND.
