1. Stresses greater than those listed under ABSOLUTE MAXIMUM RAT-
INGS may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other condi-
tions above those indicated in the operational sections of this specifica-
tion is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect reliability.
2. Vcc terminals.
3. Input terminals.
4. Output and I/O terminals.
