Instructions for Using CD4081

1. Power Supply:

   • Connect V_DD to the positive supply voltage (3V to 15V).
   • Connect V_SS to ground (0V).

2. Input Connections:

   • Ensure input voltages are within the specified range.
   • For logic high, input voltage should be at least 2V or up to V_DD.
   • For logic low, input voltage should be less than 0.5V.

3. Output Connections:

   • The output can drive loads that require current up to 800渭A (source) or sink up to 800渭A.
   • Ensure the load does not exceed the maximum output current ratings.

4. Propagation Delay:

   • The time delay between an input change and the corresponding output change is typically 35ns but can vary from 10ns to 70ns.

5. Power Dissipation:

   • Do not exceed the maximum power dissipation of 100mW to avoid overheating and potential damage.

6. Handling:

   • Handle the IC with care to avoid static damage.
   • Store in a dry place to prevent moisture damage.

7. Circuit Design:

   • Use decoupling capacitors (typically 0.1渭F) close to the power pins to filter out noise and ensure stable operation.
   • Ensure proper PCB layout to minimize signal interference and improve performance.
