'''Diode logic''' or '''Diode-resistor logic''', is a circuit style that uses [[diode]]s to construct [[Boolean logic|Boolean]] [[logic gate]]s for [[electrical circuit|circuits]]. Only non-[[inverter (logic gate)|inverting]] functions may be implemented, so it is not a complete [[logic family]]. Furthermore, such circuits are non-restoring: the output of any gate is further from a perfect ''0'' or ''1'' than(contracted; show full)[[image:Diode-OR2.png|thumb|right|Diode OR gate: example with two inputs]]
To construct an [[OR gate]] with ''n'' logic inputs, the following components are required:
* ''n'' diodes
* a [[resistor]] of much more resistance than anything you wish to turn the gate on

''n'' + 2 electrical nodes are used (counting ground as a node).

The cathode of every diode is connected to the output at Node 1. A resistor connects Node 1 to ground (low voltage, Node 2), and the remaining ''n'' nodes are the inputs.

Whenever a logic ''1'' is present at the anode of a diode, it forward-biases that diode, causing it to conduct. The input can then induce a current at the output through the diode, to cause the output voltage to be closer to ''1''.
