It provides four independent comparator channels with CMOS, MOS, or open-collector output options, covering a wide supply range from 2V to 36V (single) or ±1V to ±18V (dual). Typical applications include threshold detection, zero-crossing detectors, window comparators, and level translators in industrial control, instrumentation, and consumer electronics where through-hole assembly is preferred. ## Low quiescent current suits battery and power-sensitive designs Quiescent current maxes at 100µA across the full supply range, making this comparator a fit for power-constrained or battery-backed circuits where every microamp counts. The input bias current is 0.025µA at 5V, and input offset voltage is 5mV at 5V — typical for general-purpose comparators and adequate for rail-to-rail threshold detection without precision trimming. ## Output type and drive capability Outputs are rated for 30mA at 5V typical, with open-collector compatibility for wired-OR configurations or driving loads referenced to a different supply rail. The open-collector output also allows level shifting to higher-voltage logic or relay drivers. CMOS and MOS output options provide flexibility for direct logic interfacing without pull-up resistors. ## Temperature grade and environment Rated for 0°C to 70°C commercial temperature range, this comparator is intended for indoor, office, or appliance environments. Not specified for industrial or automotive extended-temperature operation. ## Lifecycle and sourcing The LP339N/NOPB is listed as Active with ROHS3 compliance. No end-of-life or last-time-buy notice is recorded. For current pricing and availability, submit an RFQ — the part is sourced through independent distribution and confirmed at quote time.","metaTitle":"LP339N/NOPB Quad General Purpose Comparator, 14-DIP","metaDescription":"LP339N/NOPB quad general-purpose comparator in 14-DIP.
