Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: All currents into device pins are positive; all currents out of device
pins are negative. All voltages are referenced to ground unless otherwise
specified. All typicals are given at T

Note 3: C-grade device specifications are guaranteed over the 0 C to 70 C
temperature range. In addition, C-grade device specifications are assured
over the – 40 C to 85 C temperature range by design or correlation, but
are not production tested.
