An input circuit includes an input signal transmission circuit configured to output a first transmission signal at a first output node in response to an input signal at an input node, and a Schmitt trigger inverter configured to output a second transmission signal at a second output node in response to the first transmission signal. The input signal transmission circuit includes a voltage drop element connected to the input node and configured to provide a voltage drop between the input node and a transistor having a gate to which a first supply voltage is applied. An input circuit may include an input signal transmission circuit configured to output a first transmission signal in response to an input signal and a feedback control signal, a Schmitt trigger inverter configured to output a second transmission signal in response to the first transmission signal and a second control signal, and an enable block configured to generate the feedback control signal and the second control signal in response to an enable signal.
