Instructions for Use:

1. Power Supply Requirements:

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

2. Programming:

   • The device can be programmed using standard UV-erasable EPROM programmers.
   • Follow the programming algorithm provided by the manufacturer.

3. Erasing:

   • Erasure is achieved by exposing the device to ultraviolet light through the window on the package for approximately 20 minutes.

4. Handling Precautions:

   • Handle with care to avoid damage to pins and the ceramic window.
   • Avoid exposure to high humidity and extreme temperatures outside the storage temperature range.

5. Mounting:

   • Ensure proper mounting orientation and alignment during PCB assembly.
   • Verify solder joints for reliability and electrical continuity.

6. Testing:

   • Test the device functionality after installation to ensure correct operation.
   • Use a memory tester or equivalent diagnostic tool to verify data integrity.

7. Storage:

   • Store in a dry, cool place away from direct sunlight and sources of heat when not in use.
