The LTC®1390 is a high performance CMOS 8-to-1 analog  
multiplexer. It features a 3-wire digital interface with a  
bidirectional data retransmission feature, allowing it to be  
wired in series with a serial A/D converter while using only  
oneserialport.TheinterfacealsoallowsseveralLTC1390s  
to be wired in series or parallel, increasing the number of  
MUX channels available using only a single digital port. All  
the above features are also valid when LTC1390 operates  
as a demultiplexer such as with a D/A converter.  
The LTC1390 features a typical RON of 45, typical switch  
leakage of 50pA, and guaranteed break-before-make op-  
eration. Charge injection is ±10pC maximum. All digital  
inputs are TTL and CMOS compatible when operated from  
single or dual supplies. The inputs can withstand 100mA  
fault currents.
