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 6V, TA = -40°C to +85°C.

Typical values are at +25°C, VDD = [VREG (typ.) + 1.0V]
