(Note 1) Supply Voltage Input Voltage Output Voltage Operating Free Air Temperature Range Storage Temperature Range 7V 5.5V 7V 0°C to +70°C −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.
