CMOS Analog Switches
DESCRIPTION
FEATURES
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.

Notes:
a. Application hints are for DESIGN AID ONLY, not guaranteed and not subject to production testing.
APPLICATIONS
The DG300B series of analog switches will switch positive
analog signals while using a single positive supply. This
facilitates their use in applications where only one supply is
available. The trade-offs of using single supplies are:
1) Increased RDS(on).
2) Slower switching speed. The analog voltage should not go
above or below the supply voltages which in single
operation are V+ and 0 V. (See Input Switching Threshold
vs. Positive Supply Voltage Curve.)
