NOTES:
6. 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
7. Limits should be considered typical and are not production tested.
8. Limits established by characterization and are not production tested.
