Abstract
A wired-OR logic circuit has a plurality of logic circuit connected to a common signal line. Each of the plurality of logic circuits includes an output bipolar transistor for outputting a logical output signal to the common signal line, and a constant-current source forming an emitter-follower circuit together with tile output bipolar transistor and being turned-on or turned-off in response to an output select signal. Each of the logic circuits may include a base potential setting circuit which applies different base potentials to a base of the output bipolar transistor. The outputs of the same level from all the logic circuits can be outputted to an output terminal without being influenced by voltage drops caused by distributed wiring resistances inherently existing in the signal line.
