Instructions for Use:

1. Power Supply Connection: Connect the supply voltage (Vcc) between 4.75V and 5.25V to the designated pin. Ensure proper grounding.
2. Temperature Considerations: Operate the device within the specified operating temperature range (-40°C to +85°C). Store the device within the storage temperature range (-65°C to +150°C).
3. Current Limitation: Do not exceed the maximum output current of 25mA per I/O pin to prevent damage.
4. Capacitance Management: Be aware of the input and output capacitance values when designing circuits to ensure stability.
5. Power Dissipation: Ensure that the total power dissipation does not exceed 500mW to avoid overheating.
6. Package Handling: Handle the SOP-8 package with care to avoid damage to the pins and body.
