But it can't be stressed enough that the original 4xxx chip series should be very much avoided unless solving very specific problems. In sensitive mixed analog digital applications they can be still very very helpful! Also, they come in two speeds, the standard 4000-series and the much faster HEF4000-series from NXP. Kai Klaas |
