Texas Instruments LM339 Quad Comparator Precision 1.3µs SOIC-14
Texas Instruments LM339 precision quad comparator in SOIC-14 package, 1.3µs response time, ±3mV input offset voltage, TTL and CMOS compatible outputs.
The Texas Instruments LM339 Quad Comparator is a precision comparator with a 1.3 µs response time, designed for reliable single-supply operation across a wide voltage range.
Overview
The LM339 is a low-power, low-offset voltage quad comparator engineered for operation from a single power supply across a wide voltage range. It can also be used with split power supplies, with a notably low supply current drain that remains consistent regardless of the supply voltage magnitude. Its input common-mode voltage range includes ground, enabling operation from a single supply while accommodating signals at or near 0 V.
The device is part of the LMx39 series and is designed for direct interfacing with TTL and CMOS logic families. When powered from both positive and negative supplies, it can interface directly with MOS logic and offers a lower power consumption than standard comparators.
