In addition these devices contain logic-level translation  
circuits that provide for analog signal switching of voltages  
between ±5V via 5V logic. Each switch is turned on by a  
high-level voltage on its select input (S) when the common  
Enable (E) is Low. A High E disables all switches. The digital
