This resistance adds to the 1 k external resistance and causes the voltage drop you saw. It seems like it should just be similar to an open wire between the two. The control signals will be inverted from the base input to the collector output connection.

Here is a link to the datasheet. The DMM measurement reads the value 0. I started off with both A and B grounded.

CMOS Differential 4-Channel Analog Multiplexer/Demultiplexer With Logic-Level Conversion

The R2, R3 and R4 all read 0v. Post as a guest Name. I reviewed another post that references the CD here, but it didn’t discuss the specific issues I was having. Then send 5v signals ratasheet the base of each transistor with a series base resistorand the emitter is connected to GND.

I dont know why, maybe it fried? Upon reading the data sheet this chip seems straight forward, but I’m having the hardest time hooking up the CD Dave Guenther 1 Your input logic to A,B should use the V1 voltage 12v for a high, not 5v. So at 12v Vdd you may need about a 9v minimum. Also see the switching limitations listed by jms. datashete

CD4052BE Datasheet

cd40052be I datashete hooked up the following circuit just to test the analog switching capability:. 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? Sign up using Email and Password. There are two things happening that don’t make sense to me when I test this same circuit: Email Required, but never shown. I have hooked up the following circuit just to test the analog switching capability: Post Your Answer Discard By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

It never occurred to me that logic high might be relative to Vdd. Cd4052e is as if the multiplexer isn’t switching between x0, x1, x2 or x3.

Home Questions Tags Users Unanswered. For example, it shows that with Vdd at 10v you need at least 7v for a high. Please let me know if something about this seems incorrect or is I just flat out misinterpreted the use of this chip.
