ABSTRACT:
A combination multiplexer and tristate circuit. A multiplexer circuit may be configured to receive at least a first data input and a second data input, which are selected by at least a first select signal and a second select signal, respectively. A first circuit is configured to provide an output to an output node responsive to the data input that is selected by the corresponding select signal being active. The multiplexer circuit may further use a tristate circuit, which is also coupled to receive the first select signal and the second select signal. If neither the first select signal nor the second select signal are active, then the tristate circuit is configured to prevent the first circuit from providing an output to the output node.
