DG401B_11 Datasheet, PDF (1/14 Pages) Vishay Siliconix – Low-Power, High-Speed CMOS Analog Switches

DG401B, DG403B, DG405B
Vishay Siliconix
Low-Power, High-Speed CMOS Analog Switches
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 (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, 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.
