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. ELECTRIC OPERATING CHARACTERISTICS Symbol Parameter Min. Typ. Max.
