Vishay Siliconix
CMOS Analog Switches
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.
FEATURES
