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

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.
