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.
