Absolute Maximum Ratings

c

Operating Temperature..................................–55°C to +150°C

Note:

Stresses beyond those listed under “Absolute Maxi-

mum Ratings” may cause permanent damage to the

device. This is a stress rating only and functional

operation of the device at these or any other condi-

tions 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.
