Abstract
A voltage translation device is disclosed. The voltage translation device includes an input circuit, operating in a first voltage domain, that is configured to receive an input signal. The voltage translation device also includes an output circuit, operating in a second voltage domain, that includes a latch circuit. The voltage translation device also includes a driver circuit that is controlled by the input circuit to pass a voltage from the first voltage domain to the latch circuit in order to trigger the latch circuit to output an output signal in the second voltage domain according to the input signal in the first voltage domain.
