*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.

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 5.5V,

TA = -40°C to 85°C. Typical values are at +25°C, VDD = [VREG (Typ) + 1.0V]
