The DS1672U-33 (cut-tape or tube) is the same part in different shipping media. No pinout or functional difference exists."},{"question":"Does DS1672U-33+T&R require an external crystal for timekeeping?","answer":"No. The DS1672U-33+T&R uses an internal oscillator — no external crystal is needed. The binary counter increments from an internal timebase, so the only external components are decoupling capacitors and optionally a backup battery."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/DS1672U-33TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/DS1672U-33TR when reusing this data.
