SEMICONDUCTOR TECHNICAL DATA  
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.  
N SUFFIX  
16–LEAD PLASTIC DIP PACKAGE  
CASE 648–08
