A logic gate comprises a first switch, a second switch, a data network and a keeping circuitry. The first switch is adapted to connect a logic node to a first potential responsive to a transition of an enabling signal. The second switch is adapted to connect the logic node to a second potential via an electrical path responsive to a transition of the enabling signal. The data network is serially connected within the electrical path. The keeping circuitry comprises third and fourth switches serially connected between the logic node and the first potential and being controllable separately from each other, the third switch being adapted to be closed in case a potential on the logic node assumes the first potential and to be opened in case the potential on the logic node assumes the second potential.
