Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage is within the specified range (4.75V to 5.25V).
   • Connect the Vcc pin to the positive supply and GND to ground.

2. Output Current:

   • Each output pin can source up to 20mA continuously.
   • Avoid exceeding the maximum current rating to prevent damage.

3. Temperature Considerations:

   • The device operates reliably between -40°C and 85°C.
   • Store the device between -65°C and 150°C.

4. Power Dissipation:

   • The maximum power dissipation at 25°C ambient temperature is 150mW.
   • Ensure proper heat dissipation if operating near the maximum power limit.

5. Input Voltage:

   • Input voltages should be within the range of 0V to Vcc.
   • Exceeding these limits can cause damage or malfunction.

6. Output Levels:

   • When an output is low, the voltage should not exceed 0.5V under a 20mA load.
   • When an output is high, the voltage should be at least Vcc - 0.5V under a -20mA load.

7. Handling and Storage:

   • Handle the device with care to avoid static discharge.
   • Store in a dry, cool environment to prevent moisture damage.

8. Circuit Design:

   • Use appropriate decoupling capacitors near the power pins to reduce noise and improve stability.
   • Ensure all connections are secure and free from shorts or open circuits.

9. Testing:

   • Test the device under controlled conditions to ensure it meets the specified parameters.
   • Refer to the datasheet for detailed test procedures and additional information.
