Automotive Customized
These devices are 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 outputs.

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 (Vin or Vout) 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.

* Maximum Ratings are those values beyond which damage to the device may occur.
Functional operation should be restricted to the Recommended Operating Conditions.
†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 Motorola High–Speed CMOS Data Book (DL129/D).
