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.
