ELECTRICAL CHARACTERISTICS

External components as listed in the "Typical Values" column of EXTERNAL COMPONENTS Table.

Note: Testing of all parameter is performed at 25°C. Characterisation as well as design rules used allow

correlation of tested performances at other temperatures. All parameters listed here are met in the oper-

ating range: -40 to +85°C.
