Abstract
A configurable driver/termination circuit for use in a peripheral device connected to a computer input/output controller bus. The driver/termination circuit has the pull-up current source characteristics of a three-state driver and the pull-down current sink characteristics of a open collector driver. Logic circuit defines the operating mode. In a default mode, the driver/termination circuit can function in either open collector or three-state bus designs. The circuit mode is changed by command from a host computer to explicitly operate as an open collector driver/terminator, as a three-state driver, or as an inactive high impedance. Alternatively, peripheral devices automatically select the mode which minimizes data transmission errors.
