Instructions for Use:

1. Supply Voltage (V_DD):

   • Ensure the supply voltage is within the range of 3V to 15V. The device may not function correctly outside this range.

2. Input Voltage Levels:

   • For a high input level (V_IH), the voltage should be at least 0.7 times the supply voltage.
   • For a low input level (V_IL), the voltage should be no more than 0.3 times the supply voltage.

3. Output Voltage Levels:

   • When the output is high (V_OH), it will be at least 0.85 times the supply voltage and typically around 0.9 times the supply voltage.
   • When the output is low (V_OL), it will be no more than 0.2 times the supply voltage.

4. Propagation Delay Time (t_pd):

   • The propagation delay time is the time it takes for the output to respond to a change in the input. At 5V supply voltage and 1 MHz frequency, the typical delay is 18 ns, with a minimum of 10 ns and a maximum of 30 ns.

5. Power Dissipation (P_D):

   • The maximum power dissipation at 25°C ambient temperature is 100 mW. Ensure adequate heat dissipation if operating near this limit.

6. Operating and Storage Temperature:

   • The device can operate in temperatures ranging from -40°C to 85°C.
   • For storage, the temperature range is -65°C to 150°C.

7. Handling Precautions:

   • Handle the device with care to avoid static damage. Use proper ESD protection when handling the device.
   • Ensure all connections are secure and correct to prevent damage or malfunction.

8. Application Notes:

   • The CD40109BE is a 9-stage Johnson counter with divide-by-2, 4, 8, and 16 outputs. It is suitable for use in digital circuits requiring frequency division and timing functions.
