NOTES:
4. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
5. Typical values shown reflect T_A = T_J = +25°C operation and are not guaranteed.
6. Reset is the only parameter operable within 1.2V and the minimum recommended operating supply voltage.
