Instructions for MC14489BP

1. Power Supply Connection:

   • Connect the supply voltage (VDD) between 4.5V and 5.5V to ensure stable operation.

2. Current Limiting:

   • Ensure that the output current per segment does not exceed 20mA continuously.
   • The total current per digit should not exceed 100mA continuously to prevent damage.

3. Heat Management:

   • Keep the power dissipation within 650mW to avoid overheating issues.

4. Temperature Considerations:

   • Operate the device within the temperature range of -40°C to 85°C to ensure reliability.

5. Handling and Storage:

   • Store the device in a dry environment when not in use, and handle with care to prevent electrostatic discharge (ESD).

6. Application Specific Settings:

   • Refer to the specific application notes for detailed setup instructions, especially regarding timing and interfacing with other components.

7. Pin Configuration:

   • Review the pin configuration diagram in the datasheet to correctly connect all pins according to your application requirements.
