DG9431
Vishay Siliconix
Low-Voltage Single SPDT Analog Switch
DESCRIPTION
FEATURES
The DG9431 is a single-pole/double-throw monolithic CMOS
analog device designed for high performance switching of
analog signals. Combining low power, high speed
(tON: 35 ns, tOFF: 20 ns), low on-resistance (rDS(on): 20 Ω)
and small physical size (TSOP-6), the DG9431 is ideal for
portable and battery powered applications requiring high
performance and efficient use of board space.

Low Voltage Operation (+ 2.7 to + 5 V)
Pb-free
Low On-Resistance - rDS(on): 20 Ω
Fast Switching - tON: 35 ns, tOFF: 20 ns
Low Leakage - ICOM(on): 200-pA max
Low Charge Injection - QINJ: 1 pC
Low Power Consumption
Available
RoHS*
COMPLIANT
TTL/CMOS Compatible
ESD Protection > 2000 V (Method 3015.7)
Available in TSOP-6 and SOIC-8
Lead (Pb)-Free Version is RoHS Compliant
The DG9431 is built on Vishay Siliconix’s low voltage
BCD-15 process. Minimum ESD protection, per Method
3015.7, is 2000 V. An epitaxial layer prevents latchup.
Break-before -make is guaranteed for DG9431.
BENEFITS
Each switch conducts equally well in both directions when
on, and blocks up to the power supply level when off.
•
•
•
•
Reduced Power Consumption
Simple Logic Interface
High Accuracy
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.

Notes:
a. Room = 25 °C, Full = as determined by the operating suffix.
b. Typical values are for design aid only, not guaranteed nor subject to production testing.
c. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
d. Guarantee by design, nor subjected to production test.
e. VIN = input voltage to perform proper function.
f. Difference of min and max values.
g. Guraranteed by 5-V leakage testing, not production tested.
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.
