BENEFITS
• Wide analog signal range
• Simple logic interface
• Higher accuracy
• Minimum transients
• Reduced power consumption
• Superior to DG201A, DG202
• Space savings (TSSOP)
APPLICATIONS
• Industrial instrumentation
• Test equipment

• Disk drives
• Computer peripherals
• Portable instruments
• Sample-and-hold circuits
DESCRIPTION
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.
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.
All devices feature true bi-directional performance in the on
condition, and will block signals to the supply voltages in the
off condition.
The DG201B is a normally closed switch and the DG202B is
a normally open switch. (see Truth Table.)

Notes:
a. Refer to PROCESS OPTION FLOWCHART.
b. Room = 25 °C, Full = as determined by the operating temperature suffix.
c. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.
d. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
e. Guaranteed by design, not subject to production test.
f. VIN = input voltage to perform proper function.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation
of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.
