So at 12v Vdd you may need about a 9v minimum.
CMOS Differential 4-Channel Analog Multiplexer/Demultiplexer With Logic-Level Conversion
The DMM measurement reads the value 0. While R1 reads 0. I dont know why, maybe it fried? That is actually where I would expect it to be.
I have hooked up the following circuit just to test the analog switching datashret It seems like it should just be similar to an open wire between the two. There are two things happening that don’t make sense to me when I test this same circuit: Sign up using Email and Password.
The R2, R3 and R4 all read 0v.

For example, it shows that with Vdd at 10v you need at least 7v for a high. Nedd 4, 6 The control signals will be inverted from the base input to the collector output connection.

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. Email Required, but never shown. I started off with both A and B grounded. The analog MUX isn’t equivalent to a short. Sign up using Facebook. Also see the switching limitations listed by jms.

Please let me know if something about this seems incorrect or is I just flat out misinterpreted the use of this chip. Upon cd052be the data sheet this chip seems straight forward, but I’m having the hardest time hooking up the CD Post as a guest Name.
It never datxsheet 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:.
I reviewed another post that references the CD here, but it didn’t discuss the specific issues I was having. I have hooked up the following circuit just to test the analog switching capability:.
This resistance adds to the 1 k external resistance and causes the voltage drop you saw.
