ABSTRACT:
A buffer, logic circuit, and data processing system employing fast turn-off drive circuitry for reducing leakage. Leakage current in logic circuitry is managed by coupling and decoupling the voltage potentials applied to large, high-leakage devices. Circuitry includes a low leakage logic path for holding logic states of an output after turning off high-leakage devices. A fast turn-off logic path in parallel with the low leakage logic path is used to assert each logic state in the forward direction from input to output. The large output device in each fast turn-off path is relieved of leakage stress by asserting logic states at driver inputs that cause the driver to turn OFF after the output logic state has been asserted.
