第七條　第8款1.專利、商標、著作或其他智慧財產權之內容:LEVEL SHIFT CIRCUIT AND SEMICONDUCTOR DEVICE USING LEVEL SHIFT CIRCUIT2.專利、商標、著作或其他智慧財產權之取得日期:102/11/133.取得專利、商標、著作或其他智慧財產權之成本:NT＄242,1994.其他應敘明事項:A level shift circuit, for outputting a data output signal with a secondlevel via an output inverter after a data input signal with a first level isstored in a latch, includes a level set circuit, when the output data signaloutputs with a low level, setting the output data signal to a low level inresponse to a change of the input data signal. The level set circuit isconnected to an output terminal of the output inverter, and has an NMOStransistor having a drain electrode and a source electrode coupled to aground, wherein the NMOS transistor turns on in response to the input datasignal with a high level.
