Note 1: Devices are 100% DC screened and AC production tested for functionality. Data sheet typical specifications are derived
from the average of 30 units from a typical lot, and are tested under the conditions specified for the typical specifications.
Note 2: DC current limits at -40°C are guaranteed by design and characterization.
