This device is pin compatible to standard HC405x and MC1405xB
analog mux/demux devices, but feature injection current effect
control. This makes them especially suited for usage in automotive
applications where voltages in excess of normal logic voltage are
common.
The injection current effect control allows signals at disabled analog
input channels to exceed the supply voltage range without affecting
the signal of the enabled analog channel. This eliminates the need for
external diode/ resistor networks typically used to keep the analog
channel signals within the supply voltage range.
The devices utilize low power silicon gate CMOS technology. The
Channel Select and Enable inputs are compatible with standard CMOS
or LSTTL outputs.

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.
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 circuit. For proper operation, Vin and
Vout should be constrained to the
range GND v (Vin or Vout) v 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 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 VCC current may be
drawn; i.e., the current out of the switch may contain both VCC and switch input components. The
reliability of the device will be unaffected unless the Maximum Ratings are exceeded.
