Vishay DG2788 Low voltage, low on-resistance, dual dpdt/quad spdt analog switch Datasheet

DG2788, DG2789
Vishay Siliconix
Low Voltage, Low On-Resistance, Dual DPDT/Quad SPDT
Analog Switch
DESCRIPTION
The DG2788, DG2789 are monolithic CMOS analog
switching 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
voltage process. An epitaxial layer prevents latchup. Breakbefore-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
environment, Vishay Siliconix manufactures this product
with the lead (Pb)-free device terminations and is 100 %
RoHS compliant.
FEATURES

Notes:
a. Signals on NC, NO, or COM or IN exceeding V+ will be clamped by internal diodes. Limit forward diode current to maximum current ratings.
b. All leads welded or soldered to PC board.
c. Derate 6.6 mW/°C above 70 °C
d. Manual soldering with iron is not recommended for leadless components. The miniQFN-16 is a leadless package. The end of the lead terminal
is exposed copper (not plated) as a result of the singulation process in manufacturing. A solder fillet at the exposed copper lip cannot be
guaranteed and is not required to ensure adequate bottom side solder interconnection.

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.
f. Crosstalk measured between channels.
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.
