'''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)

If a logic ''1'' is present at the cathode of every diode, then they are all reverse biased, remaining in a high-impedance state, and Node 1 is held high by the power supply through the resistor. 

If a logic ''0'' is present at any input, it forward-biases that diode and may hold Node 1 low through the diode.
