NOTES

1Stresses above those listed under “Absolute Maximum Ratings” may cause perma-

nent damage to the device. This is a stress rating only and functional operation of

the device at these or any other conditions above 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.

2Thermal characteristics: plastic N-8 package: θJA = 90°C/watt; ceramic Q-8

package: θJA = 110°C/watt, θJC = 30°C/watt. SOIC (R-8) package: θJA = 160°C

watt; θJC = 42°C/watt.
