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

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.
