Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. 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.
