Diode-or circuit
 | This article relies largely or entirely on a single source. (August 2025) |
A diode-OR circuit[1] is used in electronics to isolate two or more voltage sources. There are two typical implementations:
When a DC supply voltage needs to be generated from one of a number of different sources, for example when terminating a parallel SCSI bus, a very simple circuit like this can be used:
In digital electronics a diode-OR circuit is used to derive a simple Boolean logic function. This kind of circuit was once very common in diode–transistor logic but has been largely replaced by CMOS in modern electronics:
