Abstract
A semiconductor device comprising a first supply voltage, a second supply voltage, different from the first supply voltage; and a switching circuit. The switching circuit comprises an input configured to receive an input signal corresponding to the first supply voltage and an output configured to output an output signal corresponding to the second supply voltage. The switching circuit is a combined latch with a built-in level shifter that provides latching functionality and level shifting functionality and a leakage path is cut-off when the switching circuit is providing latching functionality.
