DESCRIPTION

The DG300A_MIL/DG301A_MIL/DG302A_MIL 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.
