Quad comparator for low-voltage, low-power signal chains
It operates from a single supply as low as 1.65 V up to 5.5 V, or from dual supplies, making it a natural fit for battery-powered instruments, 3.3 V logic systems, and 5 V industrial control boards. The open-collector, rail-to-rail output stage allows direct interfacing to logic families at any voltage within the supply range, and the 35 µA maximum quiescent current across all four comparators keeps the standing power draw negligible in always-on sensing loops.
600 ns propagation delay — what it means for control-loop timing
It is sized for signal-conditioning and threshold-detection tasks where response times in the microsecond range are acceptable.
For dual-sourcing resilience, the TLV9032DDFR is a functional peer from the same family — it offers push-pull rail-to-rail output and a faster 100 ns propagation delay, but it is a dual comparator (two elements) in a different package, so a direct drop-in replacement requires a board spin. The LM339LVPWR is the quad, open-collector option for designs that need four comparators in a single 14-TSSOP footprint.
