A gating means, biased to pass current only during signal transitions, transfers binary signals from an input signal source to a latch circuit when the signal source and the latch are operated at similar voltages. Following data transfer, the operating voltage across the latch is increased. The voltage levels of the latch output signals are correspondingly increased but the state to which the latch was set is maintained and there is no steady state current conduction through the gating means.
