ABSTRACT:
A data output circuit suitable for an integrated circuit operable at a high bit rate and having a plurality of bits of outputs. A first output transistor has a conduction path whose one electrode is connected to an output terminal, and a control electrode for controlling the conduction path in response to a first signal. A second output transistor has a conduction path whose one electrode is connected to the output terminal, and a control electrode for controlling the conduction path in response to a second signal complementary to to the first signal. A switch transistor has a conduction path having one electrode connected to the other electrode of the conduction path of the first output transistor and the other electrode connected to a first power source, and a control electrode for rendering the conduction path conductive in response to a switch signal which occurs after the first signal. A capacitor has one electrode connected to the other electrode of the first output transistor and the other electrode connected to a second power source. A plurality of such data output circuits may be mounted on a single integrated circuit, e.g., a semiconductor memory.
