DESCRIPTION

The DG300B, DG303B family of monolithic CMOS switches

feature three switch configuration options (SPST, SPDT,

and DPST) for precision applications in communications,

instrumentation and process control, where low leakage

switching combined with low power consumption are

required.

Designed on the Vishay Siliconix PLUS-40 CMOS process,

these switches are latch-up proof, and are designed to block

up to 30 V peak-to-peak when off. An epitaxial layer prevents

latchup.

In the on condition the switches conduct equally well in both

directions (with no offset voltage) and minimize error

conditions with their low on-resistance.

Featuring low power consumption (3.5 mW typ.) these

switches are ideal for battery powered applications,

without sacrificing switching speed. Designed for

break-before-make switching action, these devices are

CMOS and quasi TTL compatible. Single supply operation is

allowed by connecting the V- rail to 0 V.
