This article will explain in detail what vss and vdd mean. The content of the article is of high quality, so the editor will share it for you as a reference. I hope you will have some understanding of the relevant knowledge after reading this article.

First, in the circuit:

1. VDD means: power supply voltage (monopole device); power supply voltage (4000 series digital circuits); drain voltage (field effect transistor).

2. VCC means: power supply voltage (bipolar device); power supply voltage (74 series digital circuits); voice-controlled carrier (Voice Controlled Carrier).

3. The meaning of VSS: it usually refers to the common ground terminal voltage or the negative pole of the power supply.

4. The meaning of VEE: negative voltage power supply; the source of FET (S).

Second, on the transistor in the circuit:

1. VSS represents the power supply connected to the source (Source) of the FET.

2. VDD represents the power supply connected to the drain (Drain) of the FET.

3. VEE represents the power supply connected to the transistor emitter (Emitter).

4. VCC represents the power supply connected to the Triode collector (Collector)

Extended data:

The TIA/EIA-568-A standard specifies that vertical wiring, also known as backbone wiring, is used to connect multiple IDF (intermediate wiring closet) to the main MDF (main wiring closet). VCC usually uses optical fiber because the length of vertical cabling is usually longer than the 100m limited by Category 5e twisted pair.

In electronic circuits, VCC is the supply voltage of the circuit, and VDD is the working voltage of the chip:

VCC:C=circuit represents the meaning of the circuit, that is, the voltage of the access circuit, and D=device represents the meaning of the device, that is, the working voltage inside the device. In ordinary electronic circuits, Vcc > Vdd!

VSS:S=series means public connection, that is, negative pole.

Some IC have both VCC and VDD, and this device has a voltage conversion function.

In the "field effect" or COMS element, VDD is the drain pin of CMOS, and VSS is the source pin of CMOS. This is the component pin symbol, which does not have the name "VCC".

So much for sharing what vss and vdd mean. I hope the above content can be helpful to you and learn more knowledge. If you think the article is good, you can share it for more people to see.
