ABSTRACT:
Provided is a high-speed asynchronous digital signal level conversion circuit converting an input signal of a first voltage level into a signal of a second voltage level. The conversion circuit is able to operate at high speed by connecting first and second nodes, at which the input signal of the first voltage level is converted to the signal of the second voltage level, to a second power source voltage of the second voltage level for fast voltage level conversion when the voltage level of the input signal is changed.
