*1. Parameters must not exceed ratings, not even momentarily. If a rating is exceeded, there is a risk of IC failure,

deterioration in characteristics, and decrease in reliability.

*2. Parameters should not exceed ratings. If a rating is exceeded, there is a risk of deterioration in characteristics and decrease in reliability.

*4. Stored separately without packing material in Nitrogen or vacuum atmosphere.

*5. CE, CLK, DATA,A,AN, B, BN, Z, and ZN terminals.

*6. DATA, DA, DB, DZ, IO1, IO2, and IO3 terminals.
