Abstract

PURPOSE:To make circuit connection easy, by performing the connection between elements different in power supply voltage with one level conversion circuit, in IC logical circuits such as a DTL, a TTL and a CMOS and the like. CONSTITUTION:An FET9 is conductive by applying a gate voltage VS1 for FET driving control and an FET10 is nonconductive by not applying a gate voltage VS2 for FET driving control, and a slide terminal voltage VE1 of a variable resistor 7 is selected as a reference voltage of an operational amplifier 6, and the level comparison between the reference voltage VE1 and an input voltage VIN is made at the operational amplifier 6. A logical operation taking a VE2 as the reference voltage can be made by applying the gate voltage of VS2 only to conduct the FET10 and to unconduct the FET9.
