MAXIMUM RATINGS
*
Functional operation should be restricted to the Recommended Operating Conditions.
+Derating - Plastic DIP: - 10 mW/°C from 65° to 125°C
RECOMMENDED OPERATING CONDITIONS
However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this
high-impedance circuit. For proper operation, V
V
outputs must be left open.
Maximum Ratings are those values beyond which damage to the device may occur.
