The q denotes specifications that apply over the full operating
temperature range.
Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2: Extended grade parts are 100% tested at TA = 25°C. Performance
at – 40°C and 85°C is assured by design, characterization and correlation
with statistical process controls.
