I will use CD4051BM96 part number, DATASHEET
On page 7 is shown specs of VIH. It shows VIH of 3.5V for 5V supply (this 70% of VDD), VIH of 7V for 10V supply (70%) and VIH of 11V for 15V supply (73.3% of VDD).
I will supply the IC with 4096mV, then the VIH would be around 70% of 4.096V? Around 2.86V?
This is cause I will supply VDD with 4.096V and will put 3.3V of processor on channel selection pins. If it is supplied with 4.096V of VDD and is put 3.3V on any selection pin, will it recognize as logic high?
OBS: My input voltage on each mux input can go up to 4.096V also.
