TEXAS INSTRUMENTS LM139 LM139A LM239 LM239A LM339 LM339A LM2901 LM2901AV LM2901V QUAD DIFFERENTIAL COMPARATORS Manual(1)
Datasheet 23 pages · 568 KB · EN
The LM139, LM239, LM339, and LM2901 families are quad differential comparators that can operate from a single supply or dual supplies over a wide voltage range. They feature low supply‑current drain, low input bias and offset currents, and output compatibility with TTL, MOS, and CMOS logic.
The document provides ordering codes, package drawings, absolute‑maximum ratings, electrical characteristics, mechanical dimensions, and warranty notices for each device variant.
