Your input logic to A,B should use the V1 voltage 12v for a high, not 5v. The DMM measurement reads the value 0. Home Questions Tags Users Unanswered. I dont know why, maybe it fried? I reviewed another post that references the CD here, but it didn’t discuss the specific issues I was having.

It never occurred to me that logic high might be relative to Vdd. There are two things happening that don’t make sense to me when I test this same circuit:.

That is actually where I would expect it to be. This resistance adds to the 1 k external resistance and causes the voltage drop you saw.

The R2, R3 and R4 all read 0v. Also see the switching limitations listed by jms.

Then send 5v signals into the base of each transistor with a series base resistorand the emitter is connected to GND.

Upon reading the data sheet this chip seems straight cdd4052be, but I’m having the hardest time hooking up the Datazheet 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 dd4052be up to the Vdd level.

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. For example, it shows that with Vdd at 10v you need at least 7v for a high. Why is there a voltage difference?

Email Datasueet, but never shown. I started off with both A and B grounded. Dave Guenther 1 Nedd 4, 6 It is as if the multiplexer isn’t switching between x0, x1, x2 or x3. I have hooked up the following circuit just to test the analog switching capability:.

Please let me know if something about this seems incorrect or is I just flat out misinterpreted the use of this chip.

While R1 reads 0. I have hooked up the following circuit just to test the analog switching capability: The analog MUX isn’t equivalent to a short.

The control signals will be inverted from the base input to the collector output connection. 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: Sign up using Facebook.
