Abstract
An interface circuit for transforming a first signal varying between a low voltage and a high voltage into a second signal varying between a lower voltage and a higher voltage, the lower voltage being smaller than the low voltage and/or the higher voltage being greater than the high voltage, comprising: an inverter circuit receiving the first signal and being connected for its supply between said higher voltage and said lower voltage, one at least of these connections being performed via at least one diode, a conversion element supplied between said higher and lower voltages, and receiving the output of the inverter circuit and providing the second signal, a storage element capable of maintaining the output of the inverter circuit at said higher or lower voltage when the first signal is respectively equal to the low or high voltage.
