What is VCC and VDD in Electronics?
Electronics use VCC and VDD to refer to the power supply voltage used to power a circuit. Understanding the difference between a VCC and VDD is important to ensure a circuit is wired correctly and will function correctly.
What Does VCC Stand For?
VCC stands for Voltage Collector Collector. It is the voltage used to power a particular circuit. Bipolar junction transistors use VCC as a common power supply for the emitter and collector terminal.
What Does VDD Stand For?
VDD stands for Voltage Drain Drain. It is the power supply voltage for an integrated circuit. It is used as the reference level for analog signals, and as the power supply for both digital and analog circuits.
Difference Between VCC and VDD
- Supply Voltage: The VCC is the power supply voltage for a circuit while the VDD is the power supply voltage for an integrated circuit.
- Applications: The VCC is used with transistors while the VDD is used with integrated circuits.
- References: The VCC is used as a reference voltage for analog signals while the VDD is used as both a digital and analog reference voltage.
In conclusion, VCC and VDD are two terms used in electronics to refer to the power supply voltage. VCC is used with transistors, while VDD is used with integrated circuits. Understanding the difference between the two will ensure that a circuit is correctly wired and will operate as expected.
