Abstract
The latch device includes an RS type latch flip-flop capable of being supplied between a first supply voltage and a second supply voltage which is lower than the first supply voltage and having first and second flip-flop inputs and a flip-flop output connected to the output terminal. A control module positions the latch flip-flop in a set state or in a reset state when the first supply voltage has a first value which is lower than the low voltage then, the latch flip-flop being positioned, confers the high voltage on the first supply voltage and the low voltage on the second supply voltage and outputs and maintains the high voltage or the low voltage on the flip-flop output while avoiding outputting a prohibited logic state at the two flip-flop inputs.
