The DG211B/212B analog switches are highly improved
versions of the industry-standard DG211/212. 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 DG211B and DG212B can handle

up to
22 V, and have an improved continuous current rating
of 30 mA. An epitaxial layer prevents latchup.
All devices feature true bi-directional performance in the on
condition, and will block signals to the supply levels in the off
condition.
The DG211B is a normally closed switch and the DG212B is
a normally open switch. (See Truth Table.)
