ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ *Maximum Ratings are those values beyond which damage to the device may occur.

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

v v Vout should be constrained to the

range GND (Vin or Vout) 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.

Functional operation should be restricted to the Recommended Operating Conditions.

†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).
