一、电压的作用对象不同 VCC的供电电压作用于电路。VDD的工作电压作用于芯片。VSS的电压作用于器件内部。二、来源不同 VCC来源于集电极电源电压， 一般用于双极型晶体管。VDD来源于漏极电源电压，用于 MOS 晶体管电路, 一般指正电源。Vss来源于极电源电压，在 CMOS 电路中指负电源, 在单电源时指零伏或...
1、VDD的意思：电源电压（单极器件）；电源电压（4000系列数字电 路）；漏极电压（场效应管）。2、VCC的意思：电源电压（双极器件）；电源电压（74系列数字电路）；声控载波（Voice Controlled Carrier)。3、VSS的意思：通常指电路公共接地端电压或电源负极。4、VEE的意思：负电压供电；场效应管的源极（...
问题:What is the difference between VCC, VDD, VEE, and VSS? 有一个人的回答 Joseph NewcomerIt is a bit confusing, because Vcc was the positive voltage in bipolar logic (cc : Collector-to-Collector) and Vee was the negative reference voltage, which was 0 volts (ee : emitter-to-emitter)...
在MOS管构成的数字电路中,往往使用VDD作为供电电压的符号,在三极管构成的模拟电路中往往使用VCC作为供电电压的符号[3],到集成电路芯片以后,可能导致了VDD往往用于整个数字芯片的供电符号,VCC用于芯片内部模拟回路的供电; 4. 双字母命名法来自IEEE的标准,参考第2小节,这个应该是双字母命名法最终的标准答案; 注:下图来自...
VDD表示芯片工作时需提供的正工作电压(有些地方也用VCC表示),VSS表示负工作电压(这是在双电源供电时),一般情况下VSS端接地。 单解: VDD:电源电压(单极器件);电源电压(4000系列数字电路);漏极电压(场效应管) VCC:电源电压(双极器件);电源电压(74系列数字电路);声控载波(语音控制载波) ...
VPP: programming/erasing voltage. The difference between V and VA is: the difference between digital and analog. The difference between CC and DD is: the difference between the power supply voltage and the working voltage (usually VCC>VDD). Application Explanation ...
