  • Semiconductor integrated circuit device with voltage interface circuit
    Patent number: 6529060
    Abstract: A semiconductor integrated circuit device of an embodiment of the present invention includes a voltage converting transistor, connected between a pad and an internal circuit, for converting an input voltage applied to the pad into a voltage that is lower than an operating voltage of the internal circuit, a first pull-up transistor connected between the operating voltage and the pad, a second pull-up transistor connected between the operating voltage and a junction node connecting the voltage converting transistor with the internal circuit, and a control circuit for controlling the first and second pull-up transistors so that the first and second pull-up transistors operate complementary to each other, according to a voltage on the pad when the pad is in a floating condition.
