TLV1805: TLV1905

Part Number: TLV1805

Cannot find maximum differential input voltage on the TLV1805.  Looking for comparator for power switching between 15V supplies, and maximum differential across switch is 15V.  Common mode spec is good as is input range.  But maximum differential input voltage is unknown.  If this is not >15V, is there an alternate part?

    There are no back to back diodes between the inputs. So the differential input is limited to the supply voltage (difference between V+ and V-) + 300mV.  Each input pin has this capability specified so that’s how you can tell. If there was a differential limitation like on many high speed amplifiers, that would be specified.
