This TTL circuit uses LED indicators and must be powered by a voltage of 5 V. The capacitor determines the speed of the draw. We found it in documentation from the 90s.
This precision circuit was found in ancient American documentation. The most critical component is the...
This circuit drives a load with a delay given by the RC timing components. The circuit is from...
This project is from a 1982 documentation, based on an astable multivibrator with two transistors. The...
