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.
