Did I hook up this CD Analog Multiplexer correctly? – Electrical Engineering Stack Exchange

The analog MUX isn’t equivalent to a short. It seems like it should just be similar to an open wire between the two. The DMM measurement reads the value 0. By using our site, dataasheet acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

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:.

For example, it shows that with Vdd at 10v you need at least 7v for a high. 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. Home Questions Tags Users Unanswered.

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.

I have hooked up the following circuit just to test the analog switching capability:. The R2, R3 and R4 all datashedt 0v. Your input logic to A,B should use the V1 voltage 12v for a high, not 5v.

The control signals will be inverted from the base input to the collector output connection. 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.

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

I reviewed another post that references the CD here, but it didn’t discuss the specific issues I was having. So at 12v Vdd you may need about a 9v minimum. This resistance adds to the 1 k external resistance and causes the voltage drop you saw.

Upon reading the data sheet this chip seems straight forward, but I’m having the hardest time hooking up the CD Also see the switching limitations listed by jms.

I started off with both A and B grounded. I dont know why, maybe it fried? Dave Guenther 1
