Quase todos os circuitos integrados (CI's, … Quase todos os circuitos integrados (CI's, ou IC's em nomenclatura Inglesa) tem pelo menos dois pinos que se conectam à alimentação do circuito em que estão instalados. Estes são conhecidos como pinos de alimentação do CI. No entanto, a rotulagem dos pinos varia de acordo com a família CI e fabricante. As etiquetas mais simples são V + e V-, mas o desenho interno e tradições históricas levaram a uma variedade de outras etiquetas utilizadas. V + e V-também pode se referir à inversão (-) e não inversora (+) entradas de tensão de ICs como os amplificadores operacionais. Às vezes um dos pinos de alimentação irá ser referido como terra (abreviado "GND"). Na lógica digital, este é quase sempre o pino negativo, em circuitos integrados analógicos, é mais provável que seja um pino intermediário de tensão entre os pinos mais positivos e mais negativos. Enquanto , onde as letras subscritas denotar a diferença entre dois pontos, usa espaços reservados à procura semelhantes com subscritos, o fornecimento de notação subscrita tensão dupla carta não está diretamente ligada (embora ele pode ter sido um fator de influência).ele pode ter sido um fator de influência).
, IC power-supply pins denote a voltage and … IC power-supply pins denote a voltage and current supply terminals in electric, electronics engineering, and in Integrated circuit design. Integrated circuits (ICs) have at least two pins that connect to the power rails of the circuit in which they are installed. These are known as the power-supply pins. However, the labeling of the pins varies by IC family and manufacturer. The double subscript notation usually corresponds to a first letter in a given IC family (transistors) notation of the terminals (e.g. VDD supply for a drain terminal in FETs etc.). The simplest labels are V+ and V−, but internal design and historical traditions have led to a variety of other labels being used. V+ and V− may also refer to the non-inverting (+) and inverting (−) voltage inputs of ICs like op amps. For power supplies, sometimes one of the supply rails is referred to as ground (abbreviated "GND") – positive and negative voltages are relative to the ground. In digital electronics, negative voltages are seldom present, and the ground nearly always is the most negative voltage level. In analog electronics (e.g. an audio power amplifier) the ground can be a voltage level between the most positive and most negative voltage level. While double subscript notation, where subscripted letters denote the difference between two points, uses similar-looking placeholders with subscripts, the double-letter supply voltage subscript notation is not directly linked (though it may have been an influencing factor).h it may have been an influencing factor).

* Positive Spannung: VDD, VCC
* Negative Spannung: VSS, VEE Sie stammen aus dem angelsächsischen Sprachraum, wie das V für voltage, statt des im Deutschen üblichen U (von lateinisch urgere) für die elektrische Spannung, zeigt. Da viele große Halbleiter- und Gerätehersteller aus den USA stammen beziehungsweise stammten, haben diese Bezeichnungen weite Verbreitung gefunden. Die Index-Buchstaben (oft tiefer gestellt oder zumindest in kleinerer Schriftgröße dargestellt) D, S, C, und E entstanden dabei aus den Namen der Terminals (Anschlüsse) eines Transistors, beispielsweise Drain und Source (MOSFET) und Collector, Emitter (Bipolartransistor). Doppelte Indizes wie CC oder DD stehen in der Regel für die Versorgungsspannungen gegenüber Masse.die Versorgungsspannungen gegenüber Masse.
