DESCRIPTION
The DG2041/2042/2043 are quad single-pole/single-throw
monolithic CMOS analog switch designed for high
performance switching of analog signals. Combining low
power, fast switching, low on-resistance (r
DS(on)
:
1.0
W
@
2.7
V) and small physical size, the
DG2041/2042/2043 are ideal for portable and battery powered
applications requiring high performance and efficient use of
board space.
The DG2041/2042/2043 are built on Vishay Siliconix's new
high density low voltage process. An epitaxial layer prevents
latchup.
Each switch conducts equally well in both directions when on,
and blocks up to the power supply level when off.

Manual soldering with soldering iron is not recommended for leadless
components. The QFN is a leadless package. The end of the lead termi-
nal 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.
