DG271B
Vishay Siliconix
High-Speed Quad Monolithic SPST CMOS Analog Switch
DESCRIPTION
FEATURES
The DG271B high speed quad single-pole single-throw
analog switch is intended for applications that require low
on-resistance, low leakage currents, and fast switching
speeds.
• Fast switching tON: 55 ns
• Low charge injection: 5 pC
Built on the Vishay Siliconix’ proprietary high voltage silicon
gate process to achieve superior on/off performance, each
switch conducts equally well in both directions when on, and
blocks up to the supply voltage when off. An epitaxial layer
prevents latchup.
Pb-free
Available
• Low rDS(on): 32 Ω
• TTL/CMOS compatible
• Low leakage: 50 pA
RoHS*
COMPLIANT
BENEFITS
• Fast settling times
• Reduced switching glitches
• High precision
The DG271B has a redesign internal regulator which
improves start-up over the DG271.
APPLICATIONS
• High-speed switching
As a committed partner to the community and the
environment, Vishay Siliconix manufactures this product
with the lead (Pb)-free device terminations. For analog
switching products manufactured with 100 % matte tin
device terminations, the lead (Pb)-free “-E3” suffix is being
used as a designator.
• Sample/hold
• Digital filters
• Op amp gain switching
• Flight control systems
• Automatic test equipment
• Choppers
• Communication systems

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.
