旧设备逻辑电平转换接口时可能需要使用较小的几何尺寸工艺新设备。对于像I2C总线的双向总线系统，如电平转换器也必须是双向的，无需方向控制信号的需要。最简单的方式来解决这个问题是每个总线连接一个独立的MOS场效应管。AN10441LevelshiftingtechniquesinI2C-busdesignRev.01―18June2007ApplicationnoteDocumentinformationInfoContentKeywordsI2C-bus,levelshiftingAbstractLogiclevelshiftingmayberequiredwheninterfacinglegacydeviceswithnewerdevicesthatuseasmallergeometryprocess.ForbidirectionalbussystemsliketheI2C-bus,suchalevelshiftermustalsobebidirectional,withouttheneedofadirectioncontrolsignal.ThesimplestwaytosolvethisproblemisbyconnectingadiscreteMOS-FETtoeachbusline.NXPSemiconductors……
