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.

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.
