Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: All currents into the device pins are positive; all currents out of device pins are negative. All voltages are referenced to ground unless otherwise specified.
