NOTES:
6. Compliance to datasheet values is assured by one or more methods: production test, characterization and/or design.
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.
8. Not production tested.
