This circuit uses components of the time. We found it in a 1968 US documentation. The delay is 100 ns and the input impedance is 1 k.
In the figure we show the typical configuration of a shared line using a twisted pair where the...
This short circuit protection circuit accelerates the blown fuse in case of an output overcurrent. The...
Found in old documentation about neon lamps, this circuit shows how to add a simple blown fuse...
