Abstract:
1. A tri-state logic circuit, comprising: an input terminal for receiving an input signal; an output terminal for providing an output signal; a pull-up network for connecting the output terminal to an upper power supply voltage, responsive to the input signal; a first tri-stating nanotube switching element electrically connected in the signal path between said upper power supply voltage and said output terminal; a pull-down network for connecting the output terminal to a lower power supply voltage, responsive to the input signal; a second tri-stating nanotube switching element electrically connected in the signal path between said lower power supply voltage and said output terminal; wherein said first and second nanotube switching elements are activated and deactivated responsive to a tri-state control signal and said output terminal is tri-stated when said first and second nanotube switching elements are not activated.
