Abstract
A semiconductor integrated circuit device includes an internal circuit receiving a first power voltage including a first voltage level as a power source of the internal circuit and outputting a data signal including the first voltage level. The device further includes an interface circuit connected between the internal circuit and an output pad, the interface circuit including a plurality of low voltage transistors driven at the first power voltage. The interface circuit receives a second power voltage greater than the first power voltage as a power source of the interface circuit and the data signal, processes the data signal at least one control bias for controlling internal voltages of the low voltage transistors of no more than a maximum operating voltage, and provides the output pad with an output data signal.
