DESCRIPTION

The DG401B/403B/405B monolithic analog switches are

replacements for the popular DG401/403/405 analog switches

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.)

and provide improved performance, combining high speed (t_ON

100 ns, typ) with low power consumption make the DG401B series

ideal for portable and battery powered applications.

The DG401B/403B/405B is available in both 16-pin plastic dip

and 16-pin SOIC packages.

Built on the Vishay Siliconix proprietary high-voltage silicon-gate

process to achieve high voltage rating and superior switch on/off

performance, break-before-make is guaranteed for the SPDT

configurations.

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.

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
