  • Reduced power consumption multiplexer using self-decoding power down logic
    Patent number: 6657979
    Abstract: A multiplexer output cell (FIG. 1, 15) controls the operation of multiplexer input cells (100, 105) in a multistage multiplexer according to the value of a signal select input (130), and a state control input (180). A signal driver (125) having a number of logical outputs comparable to the number of stages in the multiplexer is used in conjunction with the state control signal (170, 175, 180) to control the power ON/OFF state of each cell in the multiplexer. The multiplexer input and output cells (100, 105, 150) which are in the signal path are set to a power ON condition, while the multiplexer input and output cells (100, 105, 150) 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.
