Product details

Quad comparator for general-purpose threshold and level detection

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.

Not specified for industrial or automotive extended-temperature operation.

No end-of-life or last-time-buy notice is recorded.

Frequently asked questions

Is LP339N/NOPB a low power comparator?

Yes, with a maximum quiescent current of 100µA, it is suited for low-power and battery-powered applications.

When sourcing LP339N/NOPB, what's the closest functional second-source?

The TLV9032DDFR is a surface-mount, dual comparator with lower input offset (0.0015mV) and wider temperature range (-40°C to 125°C), but it is not a pin-compatible or direct replacement for the LP339N/NOPB due to package and element count differences.
