DG2788 Datasheet, PDF (1/9 Pages) Vishay Siliconix – Low Voltage, Low On-Resistance, Dual DPDT/Quad SPDT Analog Switch

DG2788/DG2789
Vishay Siliconix
Low Voltage, Low On-Resistance, Dual DPDT/Quad SPDT
Analog Switch
DESCRIPTION
The DG2788/DG2789 are monolithic CMOS analog switch-
ing products designed for high performance switching of
analog signals. Combining low power, high speed, low on-
resistance and small physical size, the DG2788/DG2789 are
ideal for portable and battery powered applications requiring
high performance and efficient use of board space.
The DG2788/DG2789 are built on Vishay Siliconix’s low volt-
age process. An epitaxial layer prevents latchup. Break-
before-make is guaranteed.
The switch conducts equally well in both directions when on,
and blocks up to the power supply level when off. The
DG2788 is configured as a dual Double Pole Double Throw
switches while the DG2789 is configured as a Quad Single
Pole Double Throw. The DG2789 has one control pin for all
four SPDT switches and also has an enable pin that can turn
all switches off.
The DG2788 and DG2789 comes in a small miniQFN-16
lead package (2.6 x 1.8 x 0.75 mm).
As a committed partner to the community and the environ-
ment, Vishay Siliconix manufactures this product with the
lead (Pb)-free device terminations and is 100 % RoHS com-
pliant.
