Product details

It integrates four independent comparator circuits, each with an open-collector output stage that can sink up to 20 mA (typical). The wide supply range — 2 V to 30 V single supply, or ±1 V to ±15 V dual supply — lets it interface directly with 5 V logic rails or 24 V industrial control buses without a separate level translator.

Supply flexibility and output drive

The open-collector outputs (CMOS, MOS, TTL compatible) allow wired-OR connections and pull-up to any voltage within the supply range, making the part useful for window comparators, zero-crossing detectors, and oscillator circuits. Quiescent current is capped at 2.5 mA max across all four comparators — a reasonable budget for a multi-channel signal-conditioning block on a 5 V or 3.3 V rail. Input offset voltage is 3 mV max at 30 V supply, and input bias current is 0.25 µA max at 5 V. These figures are typical for a general-purpose comparator and adequate for threshold detection and level sensing in temperature-controlled environments (0°C to 70°C).

Frequently asked questions

What is the output type of LM339ANSRG4?

The outputs are open-collector, compatible with CMOS, MOS, and TTL logic families. This allows wired-OR connections and pull-up to any voltage within the supply range.

What is the closest pin-compatible alternative to LM339ANSRG4?

The LM339 family has many pin-compatible variants from multiple manufacturers. The standard LM339 in a 14-SOIC package shares the same footprint and pinout. Confirm the exact suffix for temperature grade and packaging before substituting.
