In the datasheet for the ISL71840SEH analog mux it says the range the VREF input is 4.5 to 5.5 V. However, if I were to use 3.3V for VREF, would it still work?
On page 23 it says that about 30% of VREF is what sets the logic threshold, so with 5V VREF the threshold would be about 1.5V, and with 3.3V VREF the threshold would be about 1V.
If a 1V logic threshold works for me, then can I use 3.3V for VREF, or are there other consequences of going below 4.5 V?
