Abstract: A semiconductor apparatus includes an internal circuit connected to a first power line to which a first power voltage is applied; a transistor including a first terminal, which is connected to a node to which an input voltage is applied, a second terminal connected to the internal circuit, and a control terminal to which a control voltage is applied; and a voltage control circuit, which is connected to the node, generating the control voltage. Further, the voltage control circuit includes a step-down circuit generating an internal voltage by lowering the input voltage applied to the node, and a switching circuit, which is connected to the first power line, generating the control voltage based on the first power voltage and the internal voltage.

Abstract: An input circuit includes an input buffer circuit using a first node as an input and a second node as an output, an N-type transistor having a source coupled to the input terminal, a drain coupled to the first node, and a gate coupled to a power supply, and a pull-up circuit provided between the first node and the power supply. The pull-up circuit is configured to make the power supply and the first node conducive with each other for a predetermined period when the input signal transitions from low to high and not to make the power supply and the first node conductive with each other when the input signal transitions from high to low.
