Abstract
Information is coupled to a data bus such as an I C data bus using a push-pull circuit. The push-pull circuit provides for communicating on the data bus at two different data rates. The push-pull circuit includes an active pull-up device that is enabled during a first push-pull mode of operation for providing a high data rate. During a second normal mode of operation, the active pull-up device is disabled providing a low data rate. When the active pull-up device is deactivated, the clock and data buses are driven by the external resistors connected thereto at a data rate lower than the data rate during the first mode.
