It's the smallest footprint in the LMV33x family, which also includes dual (LMV393) and quad (LMV339) variants — but the single channel here saves board space when you only need one threshold detector. The open-drain output lets you pull up to any voltage within the supply range, making it straightforward to interface with logic families running at different levels — 3.3V or 5V MCU inputs, for example. ## 550ns propagation delay — what that means for your loop That's fast enough for overcurrent detection in a switching regulator loop or for zero-crossing detection at line frequencies, but it won't keep up with high-speed PWM cycles above a few hundred kilohertz — the output will lag the crossing by a full cycle or more. The input offset voltage is specified at 7mV max at 5V — this sets the practical threshold accuracy floor. For a 100mV reference, the actual trip point can be off by up to 7%, so budget that into your window comparator design. Quiescent current maxes out at 100µA, and the input bias current is only 0.25µA at 5V — low enough that a high-impedance sensor divider won't load down the reference significantly. ## Temperature range and supply — industrial duty The single-supply range runs from 2.7V to 5V, so it works off a 3.3V rail with margin on both ends. No dual supply needed — the ground-referenced input common-mode range includes ground.","metaTitle":"LMV331ICT General Purpose Comparator, SC-70-5, Open-Drain","metaDescription":"LMV331ICT general-purpose comparator in SC-70-5 package.

Both share the same 2.7V to 5V supply range, open-drain outputs, and similar propagation delay (375ns for the quad vs 550ns for the single).
