Part Number: CD4052B
My customer is considering CD4052B and has a question.
Could you please advise?
About CD4052B, how is the device inside connection of COMMON X (13pin) .
Datasheet P. 17 Figure26. shows brief connection as Functional Block Diagram.
He'd like to know in more detail.
I appreciate your great help.
Why does your customer need to know the internal connections inside the device? What issue are they having with the switch?
The CDXXXXX device has a transmission gate type architecture with an NMOS FET in parallel with a PMOS FET.
You can see that the shape of the Ron vs input voltage has the same shape.
