ABSTRACT:
An output circuit includes a first, second and third field effect transistors each having a channel of a first conductivity type. The first field effect transistor includes a gate connected to a first node, a first electrode connected to a first power supply and a second electrode connected to a second node. The second field effect transistor includes a gate connected to a third node, a first electrode connected to the second node, a second electrode connected to a fourth node and a substrate connected to a fifth node. The third field effect transistor includes a gate connected to a sixth node, a first electrode connected to the third node, a second electrode connected to the fourth node and a substrate connected to the fifth node. The output circuit further includes an inverter and a fourth field effect transistor having a channel of a second conductivity type which is opposite the first conductivity type. The fourth field effect transistor includes a gate connected to the sixth node, a first electrode connected to the third node and a second electrode connected to a second power supply. The inverter includes an input terminal connected to the fourth node and an output terminal connected to the sixth node.
