DG408/409  
Vishay Siliconix  
8-Ch/Dual 4-Ch High-Performance CMOS Analog Multiplexers  
DESCRIPTION  
FEATURES  
Low On-Resistance - rDS(on): 100 Ω  
Low Charge Injection - Q: 20 pC  
Fast Transition Time - tTRANS: 160 ns  
Low Power - ISUPPLY: 10 µA  
Single Supply Capability  
The DG408 is an 8-channel single-ended analog multiplexer  
designed to connect one of eight inputs to a common output  
as determined by a 3-bit binary address (A0, A1, A2). The  
DG409 is a dual 4-channel differential analog multiplexer  
designed to connect one of four differential inputs to a  
common dual output as determined by its 2-bit binary  
address (A0, A1). Break-before-make switching action  
protects against momentary crosstalk between adjacent  
channels.  
Pb-free  
Available  
RoHS*  
COMPLIANT  
44 V Supply Max Rating  
TTL Compatible Logic  
An on channel conducts current equally well in both  
directions. In the off state each channel blocks voltages up  
to the power supply rails. An enable (EN) function allows the  
user to reset the multiplexer/demultiplexer to all switches off  
for stacking several devices. All control inputs, address (Ax)  
and enable (EN) are TTL compatible over the full specified  
operating temperature range.  
BENEFITS  
Reduced Switching Errors  
Reduced Glitching  
Improved Data Throughput  
Reduced Power Consumption  
Increased Ruggedness  
Wide Supply Ranges ( 5 V to 20 V)  
Applications for the DG408/409 include high speed data  
acquisition, audio signal switching and routing, ATE  
systems, and avionics. High performance and low power  
dissipation make them ideal for battery operated and remote  
instrumentation applications.  
APPLICATIONS  
Data Acquisition Systems  
Audio Signal Routing  
ATE Systems  
Battery Powered Systems  
High Rel Systems  
Designed in the 44 V silicon-gate CMOS process, the  
absolute maximum voltage rating is extended to 44 V.  
Additionally, single supply operation is also allowed. An  
epitaxial layer prevents latchup.
