ESD CAUTION
Specified Temperature Range −40°C to +85°C Maximum Junction Temperature 140°C ESD Human Body Model 5000 V Charged Device Model 1250 V Machine Model 400 V 1 For voltages beyond these limits, use input protection resistors. See the Input Protection section for more information. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Rev.
