DESCRIPTION
The DG401B/403B/405B monolithic analog switches are
replacements for the popular DG401/403/405 analog switches
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.
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.
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/403B/405B 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.
