TLV1704: Input voltage

The TLV1704 does not allow input voltages above the supply.

What is the threshold voltage? How many channels do you need, four or one?

I need 4 comparators and i need the inputs to withstand 20V and i am going to supply a voltage of 3.3V so if the voltage isn't there it gives a high input

What exactly do you mean with "isn't there"? At what voltage should it switch?

My schematic looks like this but as it is the tlv1704 wouldn't work because the input voltage is higher than the supplied voltage. Do you know a comparator that this would work?

Thanks Clemens for your continued support of the forums.

Thank you for the help do you know other products that exist so i can use it in my project?

Here is a search for 20 V comparators with the fail-safe feature: ti.com/amplifier-circuit/comparators/products.html#1498=Catalog&2192=Fail-safe&358max=24;40

Please note that the TLV1851 and TLV1854 are different devices.

Thank you I also found this type and think this should work for my project. I want to thank you for you'r help. But what is the diffrence between these devices because i can' find anything about the TLV1854.
