Note: Stresses above those listed as “absolute maximum ratings” may cause permanent damage to the device. This is a stress rating only and

functional operation of the device at these conditions is not implied. Exposure to maximum rating conditions for extended periods may affect

device reliability. All voltages are referenced to VSS
