Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
NOTE:
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 voltages to this high−impedance
circuit. For proper operation, Vin and Vout should be constrained to the range GND v (Vin or Vout) v VCC. Unused inputs must
always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be left open.
†Derating − SOIC Packages: – 7 mW/°C from 65° to 125°C
TSSOP Package: − 6.1 mW/°C from 65° to 125°C
