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