Functional operation should be restricted to the Recommended Operating Conditions.
Derating — Plastic DIP: – 10 mW/ C from 65 to 125 C
Ceramic DIP: – 10 mW/ C from 100 to 125 C
SOIC Package: – 7 mW/ C from 65 to 125 C
SSOP or TSSOP Package: – 6.1 mW/ C from 65 to 125 C
For high frequency or heavy load considerations, see Chapter 2 of the Motorola High–Speed CMOS Data Book (DL129/D).

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
(Vin or Vout)
Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or VCC).
Unused outputs must be left open.
