In the figure we have the way to control a flip-flop with the 4069 from positive pulses. The circuit can be used as a shield, if powered by 5 V.
The circuit shown in the figure on the right can be used on a data transfer bus with the use of an...
This timer was found in Japanese documentation from the 1960s. The transistor can be replaced by...
We found this circuit in a documentation from the 90's. The circuit can be assembled with 741...
