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.
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.
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.

APPLICATIONS
The DG300A_MIL 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.)
