Abstract
A multiplexer output cell (FIG. ) controls the operation of multiplexer input cells ( ) in a multistage multiplexer according to the value of a signal select input ( ), and a state control input ( ). A signal driver ( ) having a number of logical outputs comparable to the number of stages in the multiplexer is used in conjunction with the state control signal ( ) to control the power ON/OFF state of each cell in the multiplexer. The multiplexer input and output cells ( ) which are in the signal path are set to a power ON condition, while the multiplexer input and output cells ( ) which are not in the signal path are set to a power OFF position. In this manner, only those cells which are in the signal path are powered ON, resulting in significant power savings.
