Instructions for Using the CD4555

1. Power Supply:

   • Ensure the supply voltage (V_DD) is within the range of 3.0V to 18.0V.
   • The supply current (I_DD) should be monitored to stay within the typical range of 5渭A to 20渭A at 5V.

2. Input Levels:

   • For a valid low input (V_IL), the voltage should be below 0.8V when V_DD is 5V.
   • For a valid high input (V_IH), the voltage should be above 2.0V when V_DD is 5V.

3. Output Levels:

   • The output low voltage (V_OL) should not exceed 0.4V when sourcing 10mA at V_DD = 5V.
   • The output high voltage (V_OH) should be at least 2.4V when sinking -0.4mA at V_DD = 5V.

4. Propagation Delay:

   • The propagation delay time (t_pd) should be between 15ns and 45ns at V_DD = 5V and f_IN = 1MHz.

5. Power Dissipation:

   • The maximum power dissipation (P_D) should not exceed 100mW.

6. Handling:

   • Handle the CD4555 with care to avoid static damage.
   • Ensure all connections are secure and free from short circuits.

7. Storage:

   • Store the device in a dry, cool place to prevent moisture damage.

8. Testing:

   • Use a multimeter to verify the supply voltage and current.
   • Test the input and output levels using a signal generator and oscilloscope to ensure proper operation.

By following these guidelines, you can ensure reliable operation of the CD4555 in your circuit design.
