Abstract
An electronic level shifter device having very low power consumption includes a first voltage reference from a power supply and a second voltage reference from a ground. The shifter device includes a circuit portion with a differential cell having an output terminal and at least a first and a second input terminal. On the output terminal is a level translated signal with respect to a signal present on one of said input terminals. The device further comprises an additional circuit portion connected to a node of the differential cell and comprising at least a pull-down component inserted between said node and the second voltage reference. The pull-down component can be a MOS transistor having its conduction terminals connected between said node and the second voltage reference and its gate terminal connected to the first voltage reference of power supply by means of a series of transistors.
