NOTES:
5. Parameter magnitude at T_J = -40°C determined through characterization.
6. Limits should be considered typical and are not production tested.
7. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization
and are not production tested.
