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 |
