DG2788/DG2789
Vishay Siliconix
Low Voltage, Low On-Resistance, Dual DPDT/Quad SPDT
Analog Switch
DESCRIPTION
FEATURES
• Low Voltage Operation (1.65 V to 4.3 V)
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.

miniQFN-16 Package
• Latch-Up Current > 300 mA (JESD78)
The DG2788/DG2789 are built on Vishay Siliconix’s low volt-
age process. An epitaxial layer prevents latchup. Break-
before-make is guaranteed.
BENEFITS
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.
