This device contains protection
circuitry to guard against damage
due to high static voltages or electric
fields. However, precautions must
be taken to avoid applications of any
voltage higher than maximum rated

* Maximum Ratings are those values beyond which damage to the device may occur.
Functional operation should be restricted to the Recommended Operating Conditions.
†Derating — Plastic DIP: – 10 mW/ C from 65 to 125 C
Ceramic DIP: – 10 mW/ C from 100 to 125 C
SOIC Package: – 7 mW/ C from 65 to 125 C
TSSOP Package: – 6.1 mW/ C from 65 to 125 C
