Pick by package and manufacturer.++## Members++| Part page | Manufacturer | Package |+|---|---|---|+| [CD4040BM](https://wiki.adom.inc/ray/cd4040bm) | Texas Instruments | |+| [HEF4040BT](https://wiki.adom.inc/ray/hef4040bt) | NXP (legacy Philips) | |+| [MC14040BDR2G](https://wiki.adom.inc/ray/mc14040bdr2g) | Onsemi (Motorola legacy) | |++## The CD4000 family++The original 1970s CMOS family. Wide supply range and slow propagation. Still useful for high-voltage CMOS or coin-cell designs where speed doesn't matter. TI's CD4xxxB and CD74HC4xxx, NXP/Philips HEF4xxxB, Onsemi MC14xxx, Toshiba TC4xxxBP are all this family.++| | |+|---|---|+| Supply range | 3.0 to 18.0 V (typ. 5.0 V) |+| Input threshold | CMOS |+| 5 V tolerant inputs | yes |+| Speed class | slow |++## Provenance++Grouped by component-ocean's logic-ics parser (`definitions/logic-ics/`), which resolves each vendor MPN to a family_id. Membership is recomputed from the published pages; it is not hand-curated.
