ABSTRACT:
An input/output circuit, operable in an input mode and an output mode, for receiving data and an enable signal, the input/output circuit including an input/output terminal; a pull-up output transistor including a gate; a first logic circuit including an output node coupled to the gate of the pull-up output transistor; a pull-down output transistor including a gate; a second logic circuit coupled to the gate of the pull-down output transistor, and the second logic circuit inactivating the pull-down output transistor in the input mode; and a gate signal generation unit configured to generate a gate signal for inactivating the pull-up output transistor in accordance with the enable signal and an input signal provided from an external device to the input/output terminal in the input mode.
