  • Publication number: 20090267678
    Abstract: An integrated circuit includes: a terminal for outputting data, a driver for providing the data to the terminal, and a switch for selectively connecting/disconnecting the driver to the terminal. The disconnection of the driver reduces the capacitive load on the connection between the terminal and driver, thus reducing limitations on data rate from factors such as data reflections that reduce signal quality. Selective connection/disconnection allows the driver to be reconnected to the terminal only when needed.
