Found in Fairchild documentation from the 90s, this circuit generates signals with the characteristics given next to the diagram. The power supply must be symmetrical.
This power supply was found in a RCA publication from the 1970s. The circuit uses transistors from that...
Found in an American 1980s documentation, this circuit compares signals from two TTL sources,...
This circuit, which in our times would be called a shield, can also be used with other loads. The...
