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.

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.
