Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. †Derating − Plastic DIP: – 10 mW/ _C from 65_ to 125_C SOIC Package: – 7 mW/ _C from 65_ to 125_C TSSOP Package: − 6.1 .W/ _C from 65_ to 125_C For high frequency or heavy load considerations, see Chapter 2 of the ON Semiconductor High−Speed CMOS Data Book (DL129/D).

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high−impedance cir- cuit. 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. |
