Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
2. Cold temperature performance is guaranteed via correlation using statistical quality control. Not tested in production.
3. Guaranteed by design but not tested in production.
