Vishay Siliconix
6-Ω, Low Voltage, Dual SPST Analog Switch
DESCRIPTION
FEATURES
The DG2737, DG2738 and DG2739 are high performance,
low on-resistance analog switches of dual SPST
configuration.

•
•
•
•
•
•
Built on Vishay Siliconix's sub-micro CMOS technology, the
DG2737, DG2738, DG2739 achieve switch on-resistance of
6 Ω at 3 V V+. Its - 3 dB bandwidth is typically 720 MHz.
It can switch signals with amplitudes of up to VCC to be
transmitted in either direction.
Voltage range: 2.3 V to 4.3 V
Low on-resistance: 6 Ω typ. at 3 V
- 48 dB crosstalk at 240 MHz
RoHS
COMPLIANT
Low power consumption
Ultra small miniQFN8 package of 1.4 x 1.4 x 0.55 mm
> 300 mA latch up current per JESD78
Switch exceeds 5 kV ESD/HBM
Combining low power, high speed, low on-resistance and
small physical size, the DG2737, DG2738, DG2739 are ideal
for portable and battery powered applications requiring high
performance and efficient use of board space.
The DG2737, DG2738, DG2739 come in a small miniQFN-8
lead package (1.4 x 1.4 x 0.55 mm). As a committed partner
to the community and the environment, Vishay Siliconix
manufactures this product with the lead (Pb)-free device
terminations and is 100 % RoHS compliant.

Notes:
a. Room = 25 °C, Full = as determined by the operating suffix.
b. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
c. Typical values are for design aid only, not guaranteed nor subject to production testing.
d. Guarantee by design, not subjected to production test.
e. 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.
