I dont know why, maybe it fried?
View cd4052be datasheet:
Upon reading the data sheet this chip seems straight forward, but I’m having the hardest time vd4052be up the CD The R2, R3 and R4 all read 0v. The control signals will be inverted from the base input to the collector output connection.
While R1 reads 0. I have hooked up the following circuit just to test the analog switching capability:.
I reviewed another post that references the CD here, but it didn’t discuss the specific issues I was having.

Also see the switching limitations listed by jms. So at 12v Vdd you may need about a 9v minimum. Email Required, but never shown.
I started off with both A and B grounded. Nedd 4, 6 There are two things happening that don’t make sense to me when I test this cd4052he circuit: Here is a link to the datasheet.

Post as a guest Name. Please let me know if something about this seems incorrect or is I just flat out misinterpreted the use of this chip. It is as if the multiplexer isn’t switching between x0, x1, x2 or x3. Sign up using Email and Password. Then send 5v signals into the base of each transistor with a series base cd4052beeand the emitter is connected to GND. It seems like it should just be similar to an open wire between the two.

Your input logic to A,B should use the V1 voltage 12v for a high, not 5v. 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.
Why is there a voltage difference? This resistance adds to the 1 k external resistance and causes the voltage drop you saw.
