We found in this American documentation this circuit for activating common cathode displays. In it we have the way to cascade the 4033 to drive two displays (dozens and units).
This is one of many possible touch switch configurations using CMOS integrated circuits. The...
This circuit was found in documentation from the 1980s requiring a variable power supply from 0 to...
The integrated circuit used in this project is unusual and it includes internal transistors that...
