This is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operational listings of this specification is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability. DC CHARACTERISTICS Electrical Specifications: Unless otherwise indicated, all limits apply for VDD= [VREG(typ.) + 0.3V] to 12V, TA = -40°C to +85°C.
