Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
ELECTRICAL CHARACTERISTICS (VCC = 15 V, RT = 3.65 kW, CT = 1.0 nF, for typical values TA = + 25°C, for min/max values TA
is the operating ambient temperature range that applies [Note 2], unless otherwise noted.)
