Yes, every chip needs to be connected in the digital circuit. Chips typically require power to function properly and perform their functions. The power supply provides the necessary power and voltage to make the circuits inside the chip work properly.
In digital circuit design, one or more power supply pins are usually used to provide power to the chip. These pins are usually labeled VCC (positive power supply) and GND (ground). The VCC pins are connected to the positive power supply and the GND pins are connected to the ground to establish the circuit environment of the chip.
The voltage level and power requirements of the power supply will vary depending on the specific chip specification and application. Power requirements are usually detailed in the technical documentation or data manual of the chip, including maximum and minimum voltage ranges, power supply stability requirements, etc.
When designing and routing digital circuits, it is important to ensure that each chip is properly connected. This means connecting the VCC pins of each chip to the power supply and the GND pins to the ground to ensure the normal operation of the chip. This connection can be achieved through the power cord, power chip, power plane, etc., depending on the actual design and wiring requirements.
If the chips are not connected correctly, they may not function properly and may even cause circuit failures or unpredictable behavior. Therefore, when wiring digital circuits, it is important to ensure that each chip is correctly connected to ensure the stability and reliability of the circuit.
