Abstract: In accordance with one aspect of the invention, a semiconductor integrated circuit is provided wherein an input circuit is formed by a phase split circuit having a bipolar transistor which outputs an inverted output from the collector and a non-inverted output from the emitter. The emitter follower output circuit is driven by an inverted output of the phase split circuit. Meanwhile, an emitter load of the emitter follower output circuit is formed by a transistor, and the emitter load transistor is temporarily driven conductively by a charging current of the capacitance to be charged by the rising edge of the non-inverted output of the phase split circuit. As a second aspect of the invention, a logic circuit is formed of a logic portion and an output portion. The output portion includes an emitter follower output transistor receiving an output signal generated by the logic portion and an active pull-down transistor receiving at its base a signal supplied thereto through a capacitance element.

Abstract: Flip-flops are disposed corresponding to input circuits or output circuits of an integrated logic circuit so as to be cascaded to configure a shift register for a test and to enable a parallel transfer of data between each flip-flop and a corresponding input or output circuit. As a result, without connecting the probe to all terminals of the LSI, test signals can be supplied from some terminals via all input circuits to an internal circuit so as to conduct a diagnosis.
