CMOS Differential 4-Channel Analog Multiplexer/Demultiplexer With Logic-Level Conversion
Please let me know if something about this seems incorrect or is I just flat out misinterpreted the use of this chip.

So at 12v Vdd you may need about a 9v minimum. Post as a guest Name. Here is a link to the datasheet.
I dont know why, maybe it fried? Then send 5v signals into the datassheet of each transistor with a series base resistorand the emitter is connected to GND. There are two things happening that don’t make sense to me when I test this same circuit: For example, it shows that with Vdd at 10v you need at least 7v for a high. It is as if the multiplexer isn’t switching between x0, x1, x2 or x3. Dave Guenther 1 I reviewed another post that references the CD here, but it didn’t discuss the specific issues I was having.
I started off with both A and B grounded.
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. The DMM measurement reads the value 0. That is actually where I would expect it to be. It seems like it should just be similar to an open wire between the two.

Upon reading the data sheet this chip seems straight forward, but I’m having the hardest time hooking up the CD Sign up using Email and Password. Why is there a voltage difference?
I have hooked up the following circuit cd40552be to test the analog switching capability: Sign up using Facebook. It never occurred to me that logic high might be relative to Vdd. I have hooked up the following circuit just to test the analog switching capability:. Sign up or log in Sign up using Google.
Also see the switching limitations listed by jms.

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. While Cd452be reads 0. There are two things happening that don’t make sense to me when I test this same circuit:. The control signals will be inverted from the base input to the collector output connection.
