You use it for control signals, enable lines, and status polling where the bus timing is in the hundreds of nanoseconds, not the single-digit range. The 3.4 mA source and sink current is enough to drive a CMOS input or a small LED, but it will not switch a relay coil or a MOSFET gate directly — plan on a buffer or driver stage for any load beyond a few milliamps. No last-time-buy notice, no successor part number to chase. For a BOM that expects to run another five to ten years, this is one less obsolescence headache to track. ## Package and footprint for layout The 14-SOIC body is 3.90 mm wide — the narrow SOIC footprint, not the wide-body variant. Standard 1.27 mm pin pitch. No exposed pad, so the thermal path is through the pins only; keep the ambient below 125°C and the dissipation per gate under a few milliwatts and it stays happy.","metaTitle":"CD4001UBM NOR Gate IC, 4000B Series, 3V-18V, -55°C to 125°C","metaDescription":"CD4001UBM quad 2-input NOR gate in 14-SOIC. 3V to 18V supply, 1 µA quiescent, -55°C to 125°C.

With a 3V to 18V supply range, the CD4001UBM runs comfortably at 5V. Its logic thresholds (1V to 2.5V low, 4V to 12.5V high at 5V supply) are compatible with standard 5V CMOS and TTL outputs, though the high-level input threshold at 4V leaves less noise margin than a 74HCT part would. At 5V the propagation delay is slower than the 50 ns at 15V spec — expect roughly 100 ns to 120 ns at 5V, 50 pF."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CD4001UBM","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CD4001UBM when reusing this data.
