If the Maximum Ratings are exceeded, permanent damage may be caused to the device. This is a stress rating only, and functional operation

of the device under these or any other conditions for extended periods may affectdevice reliability. Standard CMOS handling procedures should

be employed to avoid possible damage to the device.
