ABSTRACT:
An input circuit provided in a semiconductor integrated circuit, comprises an nMOS transistor having a source connected to an input node receiving a transmission signal, a drain connected to a first node and a gate connected to a reference potential, and a pMOS transistor having a source connected to a power supply voltage, a drain connected to the first node, a first inverter having an input connected to the first node and an output connected to an output terminal, and a second inverter having an input connected to the first node and an output connected to a gate of the pMOS transistor, so that when the nMOS transistor is turned on, the pMOS transistor is rendered off, whereby no steady input current flows.
