These devices consist of four independent voltage comparators that are designed for low power consumption and high performance.
The LM139, LM239, LM339, and LM2901 families are quad differential comparators that can operate from a single supply (2 V to 36 V) or dual supplies. They feature low input bias current, low offset voltage, and output compatibility with TTL, MOS, and CMOS logic.
