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