OR Gate



In this gate any of the input is 1 so output is 1. This is basic function of this gate. Basically it will add all the input and gives output. figure below is 2 input OR gate.









Truth table of 2 input OR gate









Basically how it will work like a parallel circuit










Lamp will on by any switch ,irrespective of other switch.





2 input Transistor OR gate .





In real application IC OR gate look like above.
In one IC 4 OR gate will included.






Other Gates
AND Gate

NOT Gate

NAND Gate

NOR Gate
