Permanent device damage may occur if absolute maximum ratings are exceeded. Functional operation
should be restricted to recommended operating conditions. Exposure to excessive voltages or magnetic fields
could affect device reliability.
All voltages are referenced to V
Power dissipation capability depends on package characteristics and use environment.
