Abstract
An integrated device having a pad receiving, in a standard operative condition, an input signal having a first value and, in a test operative condition, a test voltage having a second value higher than the first value; an input stage connected to the pad and including an electronic component having a first terminal connected to the pad; a third-level detecting stage connected to the pad and supplying a logic third-level signal having a first level in presence of the input signal and a second level in presence of the test voltage; and a selector connected to a second terminal of the electronic component and structured to connect the second terminal to a reference potential in the presence of the first logic level of the third-level signal and to a biasing voltage higher than the reference potential and lower than the second value in the presence of the second logic level of the third-level signal.
