  • Multiplexer with improved channel select circuitry
    Patent number: 5045714
    Abstract: A multiplexer having an enable/disable control circuit which gates the enable/disable control signal with channel select control signals, and the resulting signal is applied to the data input gates, thereby reducing the number of inputs to the data input gates. This simplifies the circuitry and reduces the current requirements, thereby improving response time and reducing signal distortion.
