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.
