This flip-flop circuit with general purpose transistors was found in American documentation from the 1980s. The maximum operating speed depends on the transistors. Diodes are commonly used.
In the figure we have a simple amplifier stage for BC547 series transistors. The gain is...
We have here a very interesting project found in a 1982 publication. By the operation of the...
The circuit shown in the figure is suggested by National Semiconductor and makes use of an...
