DESCRIPTION/ORDERING INFORMATION  
This dual 4-to-1 CMOS analog multiplexer/demultiplexer is pin compatible with the 4052 function and also  
features injection-current effect control. This feature has excellent value in automotive applications where  
voltages in excess of normal supply voltages are common.  
The injection-current effect control allows signals at disabled analog input channels to exceed the supply voltage  
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.
