Instructions for GAL22V10D-25LPN

1. Power Supply Requirements: Ensure the supply voltage (VCC) is within the range of 4.5V to 5.5V.

2. Programming Setup:

   • Use a compatible programmer that supports GAL devices.
   • Set the programming voltage (VPP) to 12.6V ± 5%.
   • Follow the specific programming algorithm provided by the device datasheet.

3. Handling Precautions:

   • Handle the device with care to avoid static damage; use ESD protection.
   • Ensure proper orientation during installation to prevent pin misalignment.

4. Testing and Verification:

   • After programming, verify the device functionality using a logic analyzer or similar test equipment.
   • Confirm all I/O configurations match the intended design.

5. Storage and Handling:

   • Store in an anti-static environment when not in use.
   • Avoid exposure to extreme temperatures and humidity.

6. UV Erasure:

   • If reprogramming is required, expose the device to UV light for at least 20 minutes using a UV eraser designed for EPROMs and PAL devices.
