DESCRIPTION

The DG401B, DG403B, DG405B monolithic analog switches

are replacements for the popular DG401/403/405 analog

switches and provide improved performance, combining

high speed (tON: 100 ns, typ) with low power consumption

make the DG401B series ideal for portable and battery

powered applications.

Built on the Vishay Siliconix proprietary high-voltage silicongate

process to achieve high voltage rating and superior

switch on/off performance, break-before-make is

guaranteed for the SPDT configurations.

Each switch conducts equally well in both directions when

on, and blocks up to 30 V peak-to-peak when off.

On-resistance is very flat over the full ± 15 V analog range.

The DG401B has two independent SPST switches. The

DG403B has four SPST switches in NO/NC combinations.

The DG405B has four switches in two SPST pairs (see

Functional Block Diagrams and Pin Configurations on pages

1 and 2.)

The DG401B, DG403B, DG405B is available in both 16-pin

plastic dip and 16-pin SOIC packages.

As a committed partner to the community and the

environment, Vishay Siliconix manufactures this product

with the lead (Pb)-free device terminations. For analog

switching products manufactured with 100 matte tin

device terminations, the lead (Pb)-free “-E3” suffix is being

used as a designator.
