DG304B, DG306B, DG307B
Vishay Siliconix
CMOS Analog Switches
DESCRIPTION
The DG304B, DG306B and DG307B 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.
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 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.
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.
