Instructions for Use

1. Power Supply:

   • Ensure the supply voltage (Vcc) is within the specified range of 4.5V to 5.5V to prevent damage to the device.

2. Output Current Handling:

   • Each output pin can source up to 20mA. Avoid exceeding this limit to maintain reliability and longevity of the component.

3. Temperature Considerations:

   • The device is designed to operate reliably between -40掳C and 85掳C. For storage, ensure temperatures do not exceed -65掳C to 150掳C.

4. Input Handling:

   • Keep input leakage current minimal by ensuring inputs are properly terminated or pulled up/down as required. Maximum input leakage should be kept under 1渭A for optimal performance.

5. Propagation Delay:

   • Account for a typical propagation delay of 25ns when designing circuits that depend on timing accuracy.

6. Handling and Storage:

   • Handle with care to avoid static damage. Store in recommended temperature ranges to preserve functionality.

7. Installation:

   • Follow standard surface mount technology (SMT) procedures for installation. Ensure all solder joints are clean and free from defects.

8. Testing:

   • After installation, verify proper operation through functional testing at various conditions including minimum and maximum specified voltages and temperatures.
