The base product number is LM339, so any LM339 in a 14-SSOP package with the same supply range and open-collector output is a functional drop-in. The LM339DBRE4 is the Tape & Reel variant; the LM339DR (SOIC-14) differs in footprint."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM339DBRE4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM339DBRE4 when reusing this data.
