Operating Ratings indicate conditions for which the device is intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics . The guaranteed specifications apply only for the test conditions listed. ELECTRICAL CHARACTERISTICS Electrical Characteristics at IZ =10 mA and TA = +25°C unless otherwise specified.
