<p>PURPOSE:To speed up operation by providing a cut-off MOSFET between a load MOSFET and a drive MOSFET constituting a logic circuit. CONSTITUTION:The cut-off MOSFET Q21 is provided between the drive MOSFET Q22 and the load MOSFET Q23, and the drive MOSFET directly extracts a low-level voltage from the high-level voltage of the input node potential of a level converter circuit to make the extracted voltage an output signal to convert a signal of comparatively low level formed by the logic circuit to the one of high level. Accordingly, the delay time of the propagation of the signal, such as level-extraction through the cut-off MOSFET Q21 does not occur. As a result, the operation is speedified.</p> |
