Question

Which sources do you use to power and ground an IC (integrated circuit)?

1) Vcc and GND
2) Vdd and Vss
3) Vpp and Vnn
4) Vin and Vout

Answer 1

For powering an IC, Vcc and GND are typically used with bipolar technology ICs, while Vdd and Vss are used with CMOS technology ICs. Vpp and Vnn, Vin and Vout are not standard for power and ground connections.

Step-by-step explanation:

When powering an integrated circuit (IC), the most commonly used source and ground terminologies are Vcc and GND or Vdd and Vss. These pairs are not interchangeable; Vcc and GND are often used in ICs that are based on bipolar technology, while Vdd and Vss are used in CMOS technology. Vpp and Vnn could be related to programming voltage and negative supply in certain contexts, but they are not standard for power and ground. Vin and Vout are typically used to refer to input voltage and output voltage, respectively, rather than power supply and ground.

Thus, the answers that fit this context are 1) Vcc and GND, and 2) Vdd and Vss. These provide the power and reference ground needed for the IC to function properly. It's important to note that the choice between these options depends on the type of integrated circuit and its underlying technology.
