  • Patent number: 5736867
    Abstract: A reconfigurable buffer circuit capable of producing an active high or an active low output signal in accordance with a stored control parameter that is input to the buffer circuit. The reconfigurable buffer circuit has an output buffer that outputs a buffered output signal corresponding to an input signal. The reconfigurable buffer control circuit also has a control circuit that receives and stores an inputted control parameter, and receives at least one control signal from a control signal source. Based on the stored control parameter and the at least one control signal received from the control signal source, the control circuit produces the input signal.
