DESCRIPTION
The DG381B–DG390B series of monolithic CMOS analog
switches was designed for applications in instrumentation,
communications, and process control. This series is suited for
applications requiring fast switching and nearly flat
on-resistance over the entire voltage range.
switches are ideal for battery powered applications, without
sacrificing switching speed. Break-before-make switching
action is guaranteed, and an epitaxial layer prevents latchup.
Single supply operation is allowed by connecting the V– rail to
0 V.
Designed on Vishay Siliconix’ PLUS-40 CMOS process,
these devices achieve low power consumption (3.5 mW
typical) and excellent on/off switch performance. These
Each switch conducts equally well in both directions when on,
and blocks up to the supply voltage when off. These switches
are CMOS and quasi TTL logic compatible.
