Abstract
The integrated circuit connection device () enables an external component to be connected. The integrated circuit is powered by a supply voltage (V) and part of the circuit operates using at least one internal regulated voltage (V). The connection device includes two active transistors (N, P) of different conductivity connected in series between the supply voltage (V) and earth (V). The drains of these two active transistors (N, P) are connected to each other so as to form an external contact pad (). The gates of these active transistors are controlled by voltage signals that have the same amplitude (V). The connection device further includes switching means () for modifying the control signals (V) applied across the active transistor gates, without exceeding the highest voltage between the supply voltage (V) and the internal regulated voltage (V). This allows the voltage range of said integrated circuit to be adapted to an external component connected to the external contact pad ().
