At 5V, the input low threshold is 1.5V to 4V and the high threshold is 3.5V to 11V, so the gate directly accepts 5V CMOS and TTL levels with margin. At 12V or 15V rails, the same gate can interface with higher-voltage sensors or analog circuits without a level shifter. The output can source or sink 3.4 mA per gate, enough to drive a standard LED or a CMOS input on the next stage. ## Propagation delay and speed context Maximum propagation delay is 90 ns at 15V with a 50 pF load. That is slower than a 74HC gate (19 ns at 6V), but the 4000B family trades speed for noise immunity and wide supply tolerance. For clock rates below 5 MHz or for control logic, glitch filtering, and enable gating, the delay is irrelevant. For high-speed data paths, pick a 74HC or 74AC part instead. The 14-DIP (0.300\", 7.62mm) through-hole package is breadboard-friendly and hand-solderable. The supplier device package is 14-PDIP. MSL rating is not listed, but DIP packages are typically MSL 1 (no bake required). The part is ROHS3 compliant.","metaTitle":"CD4081BE 4000B Quad 2-Input AND Gate, 3V-18V, -55°C to 125°C","metaDescription":"CD4081BE quad 2-input AND gate in 14-DIP. 4000B series, 3V to 18V supply, -55°C to 125°C.

A functional equivalent in the same 4000B family is the CD4025BM96, which is a triple 3-input NOR gate — different logic function, same supply and temperature range. For a pin-compatible AND gate, the SN74HC21N is a dual 4-input AND gate in a different package and with a narrower supply range (2V to 6V) and temperature range (-40°C to 85°C). Neither is a drop-in replacement; verify the logic function and pinout against your design."},{"question":"Is CD4081BE compatible with 5V logic?","answer":"Yes. At a 5V supply, the input low threshold is 1.5V to 4V and the high threshold is 3.5V to 11V, so the gate directly accepts standard 5V CMOS and TTL output levels without external level shifting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CD4081BE","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CD4081BE when reusing this data.
