Tree-type multiplexers and methods for configuring the same
 N stage tree-type mutliplexers having multiple selects and associated processes for configuring the same are disclosed. The basic multiplexer has control signals which are disbursed throughout the tree for high performance multiplexing. Control signals are distributed such that different signals control at least one stage of the N stage tree and such that the signals controlling the selectors in each of the plurality of selector paths from the input stage to the output stage of the tree are unique. As an enhancement, circuitry for buffering the control signals provided to the input stage of the tree can be used to further reduce the capacitive load thereon.
