DG201B, DG202B  
Vishay Siliconix  
Improved Quad CMOS Analog Switches  
DESCRIPTION  
FEATURES  
22 V supply voltage rating  
The DG201B, DG202B analog switches are highly improved  
versions of the industry-standard DG201A, DG202. These  
devices are fabricated in Vishay Siliconix’ proprietary silicon  
gate CMOS process, resulting in lower on-resistance, lower  
leakage, higher speed, and lower power consumption.  
Pb-free  
TTL and CMOS compatible logic  
Low on-resistance - RDS(on): 45  
Low leakage - ID(on): 20 pA  
Single supply operation possible  
Extended temperature range  
Fast switching - tON: 120 ns  
Available  
RoHS*  
COMPLIANT  
These quad single-pole single-throw switches are designed  
for a wide variety of applications in telecommunications,  
instrumentation, process control, computer peripherals, etc.  
An improved charge injection compensation design  
minimizes switching transients. The DG201B and DG202B  
can handle up to 22 V input signals, and have an improved  
continuous current rating of 30 mA. An epitaxial layer  
prevents latchup.  
Low glitching - Q: 1 pC  
Compliant to RoHS Directive 2002/95/EC  
BENEFITS  
Wide analog signal range  
Simple logic interface  
Higher accuracy  
Minimum transients  
Reduced power consumption  
Superior to DG201A, DG202  
All devices feature true bi-directional performance in the on  
condition, and will block signals to the supply voltages in the  
off condition.  
Space savings (TSSOP)  
The DG201B is a normally closed switch and the DG202B is  
a normally open switch. (see Truth Table.)  
APPLICATIONS  
Industrial instrumentation  
Test equipment  
Communications systems  
Disk drives  
Computer peripherals  
Portable instruments  
Sample-and-hold circuits
