Product details

Quad comparator, open-collector — what you get in the 14-SOIC

The LM339ANSR: Quad differential comparator with four independent comparators. Each drives an open-collector output that sinks up to 20 mA typical.

Open-collector output — why it matters for your BOM

Open-collector output allows pull-up to a different voltage than the comparator supply. Quiescent current is 2.5 mA max.

It is a current-production part, so you can specify it into new designs without worrying about a forced redesign cycle. For BOM freeze or PCN watch, this is a low-risk line item.

Temperature grade — commercial, indoor use

Frequently asked questions

What is the output type of LM339ANSR?

The output type is CMOS, MOS, Open-Collector, and TTL compatible. The open-collector output can sink up to 20 mA typical and allows wired-AND connections.

What are the equivalents or alternatives for LM339ANSR?

The TLV9032DDFR is a newer, dual comparator with push-pull rail-to-rail outputs, 1.65 V supply, and 100 ns propagation delay, but it is not a pin-for-pin replacement — it has two elements instead of four, and its output type differs. For a direct quad open-collector replacement, stay within the LM339 family (e.g., LM339AN or LM339M).

What is LM339ANSR's listed type on this component line?

The type is listed as Differential — it is a differential comparator, meaning it compares two input voltages and outputs a digital signal based on which is higher.
