LTC1391  
8-Channel  
Analog Multiplexer with  
Cascadable Serial Interface  
U
FEATURES  
DESCRIPTION  
TheLTC ®1391isahighperformanceCMOS8-to-1analog  
multiplexer. It features a serial digital interface that allows  
several LTC1391s to be daisy-chained together, increas-  
ing the number of MUX channels available using a single  
digital port.  
Low RON: 45Ω  
Single 2.7V to ±5V Supply Operation  
Analog Inputs May Extend to Supply Rails  
Low Charge Injection  
Serial Digital Interface  
Low Leakage: ±5nA Max  
Guaranteed Break-Before-Make  
TTL/CMOS Compatible for All Digital Inputs  
The LTC1391 features a typical RON of 45, a typical  
switch leakage of 50pA and guaranteed break-before-  
make operation. Charge injection is ±10pC maximum. All  
digital inputs are TTL and CMOS compatible when oper-  
ated from single or dual supplies. The inputs can with-  
stand 100mA fault current.  
Cascadable to Allow Additional Channels  
Can Be Used as a Demultiplexer  
U
APPLICATIONS  
The LTC1391 is available in 16-pin PDIP, SSOP and  
narrow SO packages. For applications requiring 2-way  
serial data transmission, see the LTC1390 data sheet.
