LM311, LM393, LM339.
These are comperators, 1, 2 and 4 parts in one housing
Use a two-resistor attenuator on each input (four resistors total) to reduce the voltage below the common-mode voltage range of the comparator.hi,
Problem with some comparators they dont work correctly when the threshold voltage is close to the Vsupply.. that is Vs-1.5V approx.
hi,

Then make a voltage divider at the inputs for comparing, than you don't have that problem!
Yust helping everybody, nothing else !
