OR gate.This gate ORs the two inputs A and B, The Output is high if either A OR B is high. There may be a OR gate with many inputs, if one or more inputs are high then the output will be high.
Toggle the red buttons above to apply a 'high' or 'low' to inputs A and B and watch the output Q.
Truth table.
The OR gates can be built with diodes and transistors if you want to do it on your own. Then read more on how to do it here at play-hookey's digital section and Logic families. more on TTL here at Chipdir. |
