DESCRIPTION
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.)
