    摘要: A gate array LSI device having inner gate circuits whose performance is not affected by the load condition and having a large fan-out number. The inner gate circuit comprises one or more PNP-type transistors, each of which receives an input signal at the base thereof, a first NPN-type transistor whose base is connected to the emitters of the PNP-type transistors, and an output buffer circuit. The output buffer circuit includes a second NPN-type transistor, which is controlled by the signal at the emitter of the first NPN-type transistor and outputs electric charges from an output terminal, and a third NPN-type transistor, which is controlled by the signal at the collector of the first NPN-type transistor and which is connected in series with the second NPN-type transistor so as to supply a charging current to the output terminal.
