HANDLING PRECAUTIONS: These devices are CMOS and must be handled correctly to prevent damage. Package

and store only in conductive foam, anti-static tubes, or other conducting material. Use proper anti-static handling

procedures. Do not connect in circuits under "power-on" conditions, as high transients may cause permanent

damage.
