description

The DG304A through DG307A 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.

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.
