SOT-23-5 comparator with flexible output drive
The Texas Instruments LMV331M5X is a general-purpose comparator in a SOT-23-5 package (SC-74A / SOT-753 footprint). The output stage accepts CMOS, open-collector, or TTL loads — the 84 mA typical output current at 5 V drives a logic input, an LED indicator, or a small relay coil directly. The 600 ns max propagation delay keeps it fast enough for most sensor threshold and overvoltage detection loops.
Low quiescent draw for battery and portable gear
Input offset voltage is 7 mV max — adequate for general-purpose window comparators and zero-crossing detectors where sub-mV precision is not required.
Sourcing and board-fit notes
The SOT-23-5 package is a standard 5-pin footprint with 0.95 mm pitch — hand-reworkable with a fine-tip iron or hot air.
