Abstract
An integrated circuit (IC) includes an output driver circuit portion that is electrically configurable, via a configuration input, to operate in either a first mode or a second mode corresponding to an indication of a condition of the IC, such as a supply voltage indication, the first mode and the second mode having different drive characteristics. A configuration interface circuit portion as part of the improved IC is adapted to selectively override the configuration input to configure operation of the output driver circuit portion in either the first mode or the second mode based on a drive strength control input, regardless of the condition of the IC.
