*Notice: Stresses above those listed under “Maximum

Ratings” may cause permanent damage to the device. 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. Expo-

sure 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.

Typical values are at +25°C, VDD = [VREG(Typ) + 1V].
