    Abstract: Output circuit for an integrated circuit, comprising first transistor means (P2) and second transistor means (N2) connected in series between a first external voltage (Vcc) and a second external voltage (Gnd) external to the integrated circuit (100), respectively through first (L2) and second electrical connecting means (L4). The first transistor means for carry an output line (5) of the integrated circuit to the first external voltage, while the second transistor means for carry said external line of the integrated circuit to said second external voltage. The second transistor means are formed inside a first well (130) of a first conductivity type contained inside a second well (140) of a second conductivity type formed in a substrate (7) of the first conductivity type. The second well (140) of the second conductivity type is connected to said first external voltage (Vcc) through third electrical connecting means (L21) distinct from said first electrical connecting means (L2).
