Description

The DG300A-DG303A 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 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.
