ABSTRACT:
An LSI includes two internal circuits connected to different power sources, and conventional static electricity protection circuits, provided for connecting input terminals of the internal circuit connected to one power source and for connecting output terminals of the other internal circuit connected to the other power source. The LSI further includes two static electricity protection circuits each having an enhancement type field effect N channel MOS transistor provided for connecting the power source and the other power source. Thus, a potential rise or a potential fall on one input/output terminal of the internal circuit connected to the power source, which has static electricity applied with respect to the other power source as a reference, is transmitted to one of the new static electricity protection circuits through the conventional static electricity protection circuits connected to the above input/output terminal. This transmission of the potential rise or fall then causes the enhancement type FET of this new static electricity protection circuit to be rendered conductive. Accordingly, a current path is established between the above input/output terminal and the other power source, so that the static electricity applied to the above input/output terminal is absorbed in the other power source.
