LM339 Description

Short technical summary and product information.

The Texas Instruments LM339 is a versatile quad differential comparator IC. It is designed to operate from a single power supply ranging from 2 V to 36 V, or from dual supplies of ±1 V to ±18 V. The device features a low supply-current drain that is independent of the supply voltage, typically drawing only 0.8 mA.

Key electrical characteristics include a low input bias current of 25 nA typical and a low input offset voltage of 2 mV typical. The common-mode input voltage range includes ground, and the differential input voltage range can extend up to the maximum-rated supply voltage of ±36 V. The outputs are open-collector type, allowing for wired-AND logic configurations and compatibility with TTL, MOS, and CMOS logic levels.

This comparator is characterized for operation over a wide temperature range, typically from 0°C to 70°C. It is available in various package types, including SOIC, TSSOP, PDIP, SSOP, and SOP, with body sizes varying by package. Applications include industrial and automotive systems, power supervision, oscillators, peak detectors, and logic voltage translation.
