DESCRIPTION
The DG384A_MIL and DG387A_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.
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.
