About Alberto L. 转自https://miscircuitos.com/what-are-the-meaning-of-vdd-vss-vcc-vee-and-gnd/ It has always been a bit intriguing and even confusing the nomenclature of thesepower supplyvoltages (VddandVss) or (VccandVee). But Why? The following pictures are worth a thousand words… ...
VCC是双极电路的电源电压，VDD是MOS电路的电源电压，这一点已被普遍接受，这是历史的产物。同样，VEE是...
they were NPN because for some reasons I'm not going to get into, NPN were faster. Back then it made sense to someone that the positive supply voltage would be called Vcc where the "c" stands for collector. Sometimes (but less commonly) the negative supply...
BJT FET "Vxx" meaning Vcc Vdd Positive supply voltage Vee Vss Negative supply, ground Apparently this terminology originated in some way from the terminals of each type of transistor, and their common connections in logic circuits (i.e., Vcc is often applied to BJT collectors, Vee to BJT em...

一、解释VCC:C=circuit表示电路的意思,即接入电路的电压;VDD:D=device表示器件的意思,即器件内部的工作电压;VSS:S=series表示公共连接的意思,通常指电路公共接地端电压。二、说明1、对于数字电路来说,VCC是电路的供电电压,VDD是芯片的工作电压(通常Vcc>Vdd),VSS是接地点。2、有些IC既有VDD引脚又有VCC引脚,说明...
