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 HighSpeed 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 highimpedance cir-
cuit. For proper operation, V
in
and
V
out
should be constrained to the
range GND
(V
in
or V
out
)
Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or V
CC
).
Unused outputs must be left open.
