Product details

Supply voltage and temperature — where this gate fits

The 3V to 18V supply range means this gate works in systems from a 3.3V logic rail up to a 12V or 15V industrial bus. Input logic thresholds scale with supply: low-level threshold is 1V to 2.5V, high-level is 4V to 12.5V, so the gate can interface with both 5V and 12V logic families without level translation.

Package and rework — 14-TSSOP

The 14-TSSOP body is 4.40 mm wide with a 0.65 mm pitch — fine enough for compact layouts but still hand-reworkable with a hot-air station and a fine tip. The tape-and-reel option (Cut Tape also available) feeds pick-and-place without a changeover.

Frequently asked questions

Can CD4011UBPWR be replaced with CD4011BE?

The CD4011BE is the through-hole DIP version of the same quad NAND gate. The logic function is identical, but the package and footprint are different — CD4011BE is a 14-DIP, while CD4011UBPWR is a 14-TSSOP surface-mount. They are not pin-compatible on the same board without a layout change.

Is CD4011UBPWR compatible with 5V logic levels?

Yes. With a 5V supply, the input low-level threshold is 1V to 2.5V and the high-level threshold is 4V to 12.5V, so it directly interfaces with 5V CMOS and TTL logic families without level shifters.
