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 TA = 25°C. 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.
