4. Electrical Characteristics - Highlights:

️· Absolute Maximum Ratings: Defines voltage limits, storage temperatures, and other stress parameters. *Important:* Exceeding these can cause permanent damage.
️· Input Voltage Limits: Specific voltage limits apply to various signals, with some allowing temporary excursions beyond the nominal range.
️· Functional Operating Conditions: Will have a separate table defining the recommended operating conditions for reliable functionality (not fully detailed in the provided excerpt).

5. Important Cautions:

️· Input Voltage Excursions: Input voltage limits must be observed, and short excursions are permitted under specific conditions.
️· Power-On/Power-Down Sequences: Special attention is needed during these sequences when input voltages might temporarily exceed limits.
