Absolute Maximum Ratings(Note 1)
Supply Voltage
7V
Input Voltage
7V
Operating Free Air Temperature Range
0°C to +70°C
Storage Temperature Range
−65°C to +150° C
Note 1: The “Absolute Maximum Ratings” are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum ratings.
The “Recommended Operating Conditions” table will define the conditions
for actual device operation.
