Abstract
A multiplexing arrangement. The multiplexing arrangement comprises a set of data inputs wherein a first multiplexer is coupled to a first subset of the set of data inputs and a second multiplexer is coupled to a second subset of the set of data inputs. Only one of the first and second multiplexers is selected to pass one of the set of data inputs at any given time. A logic gate is coupled to the first and second data outputs, and the logic gate synthesizes an output signal for the multiplexing arrangement in response to values output by the first and second multiplexers such that the multiplexing arrangement operates as a single multiplexer. According to one embodiment, the multiplexer that is not selected to pass data has its output biased to a known state.
