ABSTRACT:
A selectable inverter circuit. An inverter circuit receives an input signal which is complemented before becoming an output signal. A pass-through circuit for setting the output signal equivalent to the input signal. An enabling circuit for providing power to the inverter circuit, in response to a selection signal. The enabling circuit also provides a charge storing circuit with a supplemental charge. The charge storing circuit releasing the supplemental charge to the inverter circuit, and so provides the inverter circuit with even more power. The enabling circuit activating the pass-through circuit and deactivating the inverter circuit in response to the first state of the selection signal. The enabling circuit deactivating the pass-through circuit and activating the inverter circuit in response to the second state of the selection signal.
