ELECTRICAL CHARACTERISTICS (continued)

BAT

= +2.2V to +5.5V, T

= -40°C to +85°C, unless otherwise noted. Typical values are at V

BAT

= +3.6V and T

= +25°C.)

(Note 2)

Note 2: Devices are tested at T

= +25°C. Specifications over temperature are guaranteed by design.

Typical Operating Characteristics

= +3.6V, T

= +25°C, unless otherwise noted.)
