The DG201B/202B analog switches are highly improved
versions of the industry-standard DG201A/202. These
devices are fabricated in Vishay Siliconix’ proprietary silicon
gate CMOS process, resulting in lower on-resistance, lower
leakage, higher speed, and lower power consumption.
These quad single-pole single-throw switches are designed
for a wide variety of applications in telecommunications,
instrumentation, process control, computer peripherals, etc.
An improved charge injection compensation design minimizes
switching transients. The DG201B and DG202B can handle

All devices feature true bi-directional performance in the on
condition, and will block signals to the supply voltages in the
off condition.
The DG201B is a normally closed switch and the DG202B is
a normally open switch. (See Truth Table.)
