摘要： A voltage translator circuit includes an input stage adapted for receiving an input signal referenced to a first voltage supply, a first latch circuit adapted for connection with a second voltage supply and operative to at least temporarily store a logic state of the input signal, and a voltage clamp coupled between the input stage and the first latch circuit. The voltage clamp is operative to set a maximum voltage across the input stage to a prescribed level. The voltage translator circuit generates a first output signal at a first output formed at a junction between the first latch circuit and the voltage clamp. A second latch circuit is connected to the first output in a feedback configuration. The second latch circuit is operative to retain a logical state of the first output signal as a function of at least a first control signal supplied to the second latch circuit regardless of a state of the first voltage supply.
