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.","metaTitle":"TI LM339ADRE4 quad differential comparator, 2V–30V supply","metaDescription":"Texas Instruments LM339ADRE4 quad differential comparator in 14-SOIC.

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."},{"question":"What is the difference between LM339ADRE4 and LM339AD?","answer":"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.
