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

Sample-and-hold circuits
The DG401B, DG403B, DG405B is available in both 16-pin
Test equipment
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.
