Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of
these limits are exceeded, device functionality should not be assumed, damage may occur and
reliability may be affected.

Functional operation above the stresses listed in the Recommended Operating Ranges is not
implied. Extended exposure to stresses beyond the Recommended Operating Ranges limits may
affect device reliability.
*For voltage drops across switch greater than 1.2 V (switch on), excessive V
CC
current may be
drawn; i.e., the current out of the switch may contain both V
CC
and switch input components. The
reliability of the device will be unaffected unless the Maximum Ratings are exceeded.

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, V
in
and
V
out
should be constrained to the
range GND v (V
in
or V
out
) v V
CC
.
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.
