DG441, DG442  
Vishay Siliconix  
Quad SPST CMOS Analog Switches  
FEATURES  
DESCRIPTION  
Halogen-free according to IEC 61249-2-21  
Definition  
The DG441, DG442 monolithic quad analog switches are  
designed to provide high speed, low error switching of analog  
and audio signals. The DG441 has a normally closed  
function. The DG442 has a normally open function.  
Combining low on-resistance (50 , typ.) with high speed  
(tON 150 ns, typ.), the DG441, DG442 are ideally suited for  
upgrading DG201A/202 sockets. Charge injection has been  
minimized on the drain for use in sample-and-hold circuits.  
Low on-resistance: 50   
Low leakage: 80 pA  
Low power consumption: 0.2 mW  
Fast switching action - tON: 150 ns  
Low charge injection - Q: - 1 pC  
DG201A/DG202 upgrades  
TTL/CMOS-compatible logic  
Single supply capability  
Compliant to RoHS Directive 2002/95/EC  
To achieve high voltage ratings and superior switching  
performance, the DG441, DG442 are built on Vishay  
Siliconix’s high-voltage silicon-gate process. An epitaxial  
layer prevents latchup.  
BENEFITS  
Less signal errors and distortion  
Reduced power supply requirements  
Faster throughput  
Improved reliability  
Reduced pedestal errors  
Simplifies retrofit  
Each switch conducts equally well in both directions when  
on, and blocks input voltages to the supply levels when off.  
Simple interfacing  
APPLICATIONS  
Audio switching  
Battery powered systems  
Data acquisition  
Hi-Rel systems  
Sample-and-hold circuits  
Communication systems  
Automatic test equipment  
Medical instruments
