Usage:

1. Connect the analog signal lines to the input and output pins of the CD4066.
2. Apply the control signal to the appropriate logic control pins to switch the analog paths.
3. Ensure that the analog input voltage and control signals are within the specified range to prevent damage and ensure proper operation.

Caution:

• Verify that the analog input voltage does not exceed the supply voltage (V_DD) to avoid damage to the IC.
• Ensure that the control logic signals are properly interfaced with the CD4066 to achieve reliable switching performance.
• Follow the datasheet recommendations for external components and circuit design to ensure optimal performance.
