All inputs contain protection circuitry to prevent damage due to high static
discharges. Care should be exercised to prevent unnecessary application of voltages in
excess of the allowable limits. ~1
COMMENT ^
Stresses above those listed under "Absolute Maximum Ratings" may cause permanent
damage to the device. These are stress ratings only. Functional operation of this device j j
at these or any other conditions above those indicated in the operational sections of this Lj
specification is not implied and exposure to absolute maximum rating conditions for
extended periods may affect device reliability. j /
