Four open-collector outputs let you wire-OR multiple channels or translate between 5V logic and a 24V PLC input card without a level shifter. Supply range spans 2V to 28V (or ±1V to ±14V split), so it runs off the same rail as the sensors it monitors — no secondary regulator needed. ## What the ratings mean for the BOM Output current is 20mA typical per channel. Quiescent current is 800µA maximum across all four comparators. ## Package and mounting 14-SOIC body, 3.90 mm wide, 0.154\" pitch. Surface-mount reflow compatible. The supplier device package is also 14-SOIC — no footprint mismatch between the order code and the land pattern. Tube shipment, so plan for pick-and-place tray loading if you are running high-volume reels.","metaTitle":"LM3302D Quad Differential Comparator, 14-SOIC, -40 to 85°C","metaDescription":"LM3302D quad general-purpose comparator in 14-SOIC.

The key difference is the supply range: LM3302D runs from 2V to 28V, while LM339 typically starts at 2V and goes to 36V. Check your rail maximum before substituting."},{"question":"Is LM3302D RoHS compliant?","answer":"Yes — ROHS3 compliant per the listing. No lead, mercury, cadmium, or other restricted substances above threshold."},{"question":"What is the difference between LM3302 and LM339?","answer":"The LM3302D is a lower-voltage variant of the LM339 quad comparator. LM3302D supply max is 28V; LM339 goes to 36V. Both share the same pinout and open-collector output stage. For 24V industrial rails either works; for 28V or higher rails the LM339 is the correct choice."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3302D","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3302D when reusing this data.
