It's the kind of part you reach for when a single comparator won't cover both channels and you don't have room for two separate SOIC-8s. Typical applications include threshold detection, zero-crossing detectors, and window comparators in power supplies, motor drives, and industrial control boards where you need two comparators side by side without doubling the footprint. ## Active lifecycle — no LTB clock ticking The LMX393AUA carries an Active product status, so there's no last-time-buy window closing or end-of-life notice to worry about for current production runs. If your BOM needs to meet RoHS directives (EU, China, etc.), this part won't pass without an exemption. For legacy designs or military/aerospace builds where leaded solder is still permitted or exempted, it's a straightforward drop-in. No second-source alternate is listed in the available records, so dual-sourcing would require qualification of a functionally equivalent comparator from another vendor. ## What the ratings mean for your BOM The supply voltage range is not listed in the available specs. Verify against the full datasheet.","metaTitle":"LMX393AUA Dual Comparator, Tiny-Pack, Active","metaDescription":"LMX393AUA dual tiny-pack comparator from National Semiconductor.

The core comparator function is the same — two independent comparators with open-collector outputs — but the LMX393AUA comes in a smaller footprint package, saving board area at the expense of slightly tighter layout constraints. The LM393 is typically available in larger packages like SOIC-8 or DIP-8, which are easier to hand-solder and route on a two-layer board."},{"question":"Is LMX393AUA RoHS compliant?","answer":"No, the LMX393AUA is marked as RoHS non-compliant. It contains lead and cannot be used in products requiring RoHS compliance unless an exemption applies. For RoHS-required builds, look for a lead-free comparator alternative."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LMX393AUA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LMX393AUA when reusing this data.
