DG401B, DG403B, DG405B Vishay Siliconix Low-Power, High-Speed CMOS Analog Switches DESCRIPTION FEATURES The DG401B, DG403B, DG405B monolithic analog switches 44 V supply max rating are replacements for the popular DG401/403/405 analog 15 V analog signal range switches and provide improved performance, combining On-resistance - R : 23 DS(on) high speed (t : 100 ns, typ) with low power consumption ON Low leakage - I : 40 pA D(on) make the DG401B series ideal for portable and battery Fast switching - t : 100 ns powered applications. ON Upgrade to DG401B, DG403B, DG405B Built on the Vishay Siliconix proprietary high-voltage silicon- TTL, CMOS compatible gate process to achieve high voltage rating and superior switch on/off performance, break-before-make is Single supply capability guaranteed for the SPDT configurations. BENEFITS Each switch conducts equally well in both directions when Wide dynamic range on, and blocks up to 30 V peak-to-peak when off. Break-before-make switching action On-resistance is very flat over the full 15 V analog range. (DG403B only) The DG401B has two independent SPST switches. The DG403B has four SPST switches in NO/NC combinations. Simple interfacing The DG405B has four switches in two SPST pairs (see APPLICATIONS Functional Block Diagrams and Pin Configurations on pages Audio and video switching 1 and 2.) Sample-and-hold circuits The DG401B, DG403B, DG405B is available in both 16-pin Test equipment plastic dip and 16-pin SOIC packages. PBX, PABX 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.
