DESCRIPTION
The DG381A_MIL and DG390A_MIL monolithic CMOS
analog switches were 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.
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
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.
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.
