Soo anybody wanna talk electronics?
I am looking for a ttl compatible (3.3v) cmos that is capable of switching up to 20v
Basically I need a spdt analog mux demux for some shenanigans I am designing..
I can provide schematic diagrams if it helps.
I am also curious if I use a more widely available cmos that is only rated to 12v single ended can I clamp the input voltage with a zener to 11.8v or will this affect the upstream voltage in the system?
Usage is automotive, this is meant to be used as a way to isolate differing circuit parts from one another for usage of one input wire and one adc for multiple circuit functions (gui controlled selection between analog input and digital switching)
