19. Electrical Characteristics
19.1 Absolute Maximum Ratings*
19.2 DC Characteristics
Operating Temperature.................................. -55°C to +125°C
*NOTICE: Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent dam-
age to the device. This is a stress rating only and
functional operation of the device at these or
other conditions beyond those indicated in the
operational sections of this specification is not
implied. Exposure to absolute maximum rating
conditions for extended periods may affect
device reliability.
