ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ Maximum ratings are those values beyond which device damage can occur. Maximum ratings

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 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.

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 mW/_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).
