Abstract
A semiconductor integrated circuit receives and transmits signals at more than one set of VH/VL voltage levels. The integrated circuit includes a core region, an input pad, an output pad, peripheral circuitry, and a plurality of power supply lines each at power supply voltage levels V1, V2, V3 . . . Vm. The integrated circuit also includes input circuitry and output circuitry each of which have buffers and translators. The availability of the power lines each at power supply voltage levels V1, V2, V3 . . . Vm and translators allows for the present circuit to transmit and receive various sets of input signals and output signals, all within the same integrated circuit.
