    AI Overview
    The TLV3491AIDBVR is a Texas Instruments nanopower (0.8 µA), 1.8 V to 5.5 V, push-pull output comparator in a
    5-pin SOT-23 package. 
    Direct, authorized replacements and alternatives from Texas Instruments include: 
    • TLV3491AIDBVT: The same chip (TLV3491) in the same SOT-23 package, just with a different tape-and-reel quantity (T = 250 units, R = 3000 units).
    • TLV3491AIDBVRG4: Green/RoHS compliant version of the same chip.
    • TLV3491AID / TLV3491AIDR: The same comparator functionality but in an 8-pin SOIC package. 
    Other similar low-power/nanopower comparators that might serve as functional replacements include: 
    • TLV3691: 0.9 V to 6.5 V, 75 nA nanopower comparator.
    • TLV3501: A faster alternative if the 6-µs response time of the 3491 is not sufficient. 
    Package and Pinout Notes:
    The original chip is in a SOT-23-5 (DBV) package. Ensure any replacement uses this same package for direct PCB fitment.
