It accepts a wide supply range of 2 V to 30 V in single-supply mode, or ±1 V to ±15 V with split rails, making it adaptable to both 5 V logic systems and higher-voltage industrial rails. The open-collector output stage (also listed as CMOS, MOS, and TTL compatible) allows wired-OR connections and level shifting to different supply domains — a common requirement in threshold detection and window comparators. Maximum quiescent current draw is 2.5 mA across all four comparators — the part stays cool in dense boards and keeps the thermal budget low even when all channels are switching. Input offset voltage is specified at 5 mV max at 30 V supply, and input bias current is 0.25 µA max at 5 V — these are the numbers that set the detection threshold accuracy in precision applications like battery undervoltage lockout or zero-crossing detectors. The 14-TSSOP body (0.173-inch, 4.40 mm width) is a standard fine-pitch surface-mount footprint. The wide supply range and open-collector outputs make it a drop-in for many legacy 339-type designs.","metaTitle":"LM339PWRG4 Quad Differential Comparator, 2V-30V, 14-TSSOP","metaDescription":"TI LM339PWRG4 quad differential comparator. 4 elements, 2V to 30V supply, 0°C to 70°C.

The primary difference is the package: LM339PWRG4 comes in a 14-TSSOP (thin shrink small outline package), while LM339DR is in a 14-SOIC. The TSSOP offers a smaller footprint (4.40 mm body width vs 3.91 mm for SOIC) with a finer pin pitch, which may affect PCB layout and assembly yield. Functionally they are interchangeable."},{"question":"Is LM339PWRG4 RoHS compliant?","answer":"The LM339PWRG4 is a TI part with the 'G4' suffix, which historically indicates a lead-free / RoHS-compliant finish."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM339PWRG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM339PWRG4 when reusing this data.
