Abstract

A voltage level switch device employing a transistor circuit, consisting of a pair of transistors whose emitters are connected to each other and, through a resistor, to a first terminal of a supply voltage, to the passage of the collectors, with interleaving of respective resistors, they are connected to a second terminal of the supply voltage and the base of the first transistor is connected to the input voltage, characterized in that a third transistor is provided whose emitter is connected to both the base of the second transistor as also, in series with a resistor, with the voltage terminal null, while its collector, through a control element, leads the second terminal of the supply voltage and its base is connected to the collector of the first transistor.
