The wide supply range — 2 V to 30 V single supply, or ±1 V to ±15 V dual supply — lets it interface directly with 5 V logic rails or 24 V industrial control buses without a separate level translator. ## Supply flexibility and output drive The open-collector outputs (CMOS, MOS, TTL compatible) allow wired-OR connections and pull-up to any voltage within the supply range, making the part useful for window comparators, zero-crossing detectors, and oscillator circuits. Quiescent current is capped at 2.5 mA max across all four comparators — a reasonable budget for a multi-channel signal-conditioning block on a 5 V or 3.3 V rail. Input offset voltage is 3 mV max at 30 V supply, and input bias current is 0.25 µA max at 5 V. These figures are typical for a general-purpose comparator and adequate for threshold detection and level sensing in temperature-controlled environments (0°C to 70°C).","metaTitle":"TI LM339ANSRG4 Quad Differential Comparator, 14-SOIC","metaDescription":"Texas Instruments LM339ANSRG4 quad differential comparator in 14-SOIC. 2V to 30V supply, open-collector output, 20mA output current.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Type":"Differential","Series":"-","Package":"Tape & Reel (TR)","Hysteresis":"-","Output Type":"CMOS, MOS, Open-Collector, TTL","Mounting Type":"Surface Mount","Package / Case":"14-SOIC (0.209\\\", 5.30mm Width)","lifecycle_stage":"eol_hot","CMRR, PSRR (Typ)":"-","Number of Elements":"4","Base Product Number":"LM339","Operating Temperature":"0°C~70°C","Current - Output (Typ)":"20mA","Propagation Delay (Max)":"-","Supplier Device Package":"14-SO","Current - Quiescent (Max)":"2.5mA","Current - Input Bias (Max)":"0.25µA @ 5V","Voltage - Input Offset (Max)":"3mV @ 30V","Voltage - Supply, Single/Dual (±)":"2V ~ 30V, ±1V ~ 15V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/01d017d5c3c4e323e53d322683ed2720.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM339ANSRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the output type of LM339ANSRG4?","answer":"The outputs are open-collector, compatible with CMOS, MOS, and TTL logic families.
