This document details the characteristics of LM139/LM139A/LM239/LM239A/LM339/LM339A/LM2901/LM2901AV/LM2901V four-way differential comparators, including single-supply or dual-supply power supply, operating temperature range, maximum supply voltage, supply current, input bias current, input offset current, input offset voltage, common-mode input voltage range, differential input voltage range, output saturation voltage, output compatibility, etc.
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.
