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 (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 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.
