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
For high frequency or heavy load considerations, see Chapter 2 of the Motorola High–Speed CMOS Data Book (DL129/D).

This device contains circuitry to
protect the inputs against damage
due to high static voltages or electric
fields referenced to the GND pin,
only. Extra precautions must be
taken to avoid applications of any
voltage higher than maximum rated
voltages to this high–impedance
circuit. For proper operation, the
ranges GND

mended.
Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or VCC).
