DG417/418/419  
Vishay Siliconix  
Precision CMOS Analog Switches  
DESCRIPTION  
FEATURES  
The DG417/418/419 monolithic CMOS analog switches  
were designed to provide high performance switching of  
analog signals. Combining low power, low leakages, high  
speed, low on-resistance and small physical size, the  
DG417 series is ideally suited for portable and battery  
powered industrial and military applications requiring high  
performance and efficient use of board space.  
15 V Analog Signal Range  
Pb-free  
On-Resistance - rDS(on): 20 Ω  
Available  
Fast Switching Action - tON: 100 ns  
Ultra Low Power Requirements - PD: 35 nW  
TTL and CMOS Compatible  
RoHS*  
COMPLIANT  
MiniDIP and SOIC Packaging  
44 V Supply Max Rating  
BENEFITS  
To achieve high-voltage ratings and superior switching  
performance, the DG417 series is built on Vishay Siliconix’s  
high voltage silicon gate (HVSG) process. Break-before-  
make is guaranteed for the DG419, which is an SPDT  
configuration. An epitaxial layer prevents latchup.  
Wide Dynamic Range  
Low Signal Errors and Distortion  
Break-Before-Make Switching Action  
Simple Interfacing  
Reduced Board Space  
Improved Reliability  
Each switch conducts equally well in both directions when  
on, and blocks up to the power supply level when off.  
APPLICATIONS  
Precision Test Equipment  
Precision Instrumentation  
Battery Powered Systems  
Sample-and-Hold Circuits  
Military Radios  
The DG417 and DG418 respond to opposite control logic  
levels as shown in the Truth Table.
