DESCRIPTION
The DG304A_MIL through DG307A_MIL series of monolithic
CMOS switches were designed for applications in
communications, instrumentation and process control. This
series is well suited for applications requiring fast switching
and nearly flat on-resistance over the entire analog range.
applications,
without
sacrificing
switching
speed.
Break-before-make switching action is guaranteed, and an
epitaxial layer prevents latchup. Single supply operation (for
positive switch voltages) is allowed by connecting the V– rail
to 0 V.
Designed on the Vishay Siliconix PLUS-40 CMOS process to
achieve low power consumption and excellent on/off switch
performance, these switches are ideal for battery powered
Each switch conducts equally well in both directions when on,
and blocks up to the supply voltage when off. These switches
are CMOS input compatible.
