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

and decrease in reliability.

*2. Parameter must not exceed the rating on average. If the rating is exceeded, there is a risk of IC failure, deterioration in characteristics and decrease in

reliability.

*3. Parameter should not exceed the rating. If the rating is exceeded, there is a risk of deterioration in characteristics and decrease in reliability.

*4. VDD value is the recommended operating voltage rating.

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

*6. SEL0, SEL1, ZSEL,A,AN, B, BN, Z, and ZN terminals.

*7. DA, DB, and DZ terminals.

*8. 114.3×76.2×1.6mm, 150% wiring ratio, FR-4 4-layer board (with thermal pad connections). Dissipation will vary due to differences in board

specifications and footprint pattern.
