Product details

Quad differential comparator with wide supply flexibility

It accepts a single supply from 2 V to 30 V or a dual supply from ±1 V to ±15 V, making it adaptable to both single-rail and split-rail designs across 5 V, 12 V, and 24 V systems. Each output is open-collector, rated for 20 mA typical sink current, which allows wired-OR connections and level translation to TTL, CMOS, or MOS logic families. The maximum quiescent current is 2.5 mA across the four channels — a reasonable budget for a general-purpose comparator in non-battery-critical applications.

14-SOIC footprint and Tape & Reel supply

Housed in a 14-SOIC package (0.154-inch body width, 3.90 mm), the LM339ADRE4 shares the industry-standard quad comparator footprint.

Frequently asked questions

Can LM339ADRE4 replace LM339D on a 14-SOIC board?

Both parts share the same 14-SOIC package and the industry-standard quad comparator pinout. The LM339ADRE4 is the 'A' grade variant with tighter offset voltage (3 mV max) compared to the standard LM339D. It is a drop-in replacement electrically and mechanically for any 14-SOIC LM339-family comparator.

What is the difference between LM339ADRE4 and LM339AD?

The LM339ADRE4 and LM339AD are electrically identical — the 'R' in the suffix indicates Tape & Reel packaging, while the LM339AD is typically supplied in tube or bulk. The die, specifications, and package are the same.
