A method and apparatus for a programmable output interface which includes a switching device and an output driver. The switching device receives an enable signal, a selection signal, and an information signal. The switching device passes the enable signal or the information signal to an output of the switching device based on the selection signal. An output of the output driver is enabled by the output of the switching device. The output driver receives the information signal and passes the information to the output of the output driver if the output driver is enabled. The selection signal is usable to convert the output driver output to a tri-state output or an open collector output. The enable signal is usable to enable and disable the tri-state when the output driver output is a tri-state output.
