These are stress ratings only and operation at these conditions for extended periods may affect device reliability. This product utilizes CMOS technology with static protection; however proper ESD prevention procedures should be used when handling this product. Damage can occur when exposed to extremely high static electrical charge. Telephone 610.992.0727 Page 2 of 7 Facsimile 610.992.0734 This datasheet contains PROPRIETARY information.
