In the figure we have the way to implement a logic gate or (OR) with an LM393. The circuit must be powered by a symmetrical source and other operational ones can be used.
This circuit was suggested by Analog Devices in its manual of linear integrated circuits. Many...
This type of configuration can be seen elsewhere in this section. This is from a 1965 General...
This fiber optic receiver was obtained from a 1978 documentation. We can use any modern...
