This circuit is designed to control static loads fed by direct voltage. The circuit is from Motorola documentation from 1968. Equivalent SCRs may be used depending on the load.
This bistable or flip-flop is triggered by a negative pulse applied to the collector of the...
This circuit is old, but it can be easily implemented with TIP42 transistors and a 6 + 6 V or 9 +...
This circuit is from the LM111 manual of the 1980s. The component no longer exists, but...
