Description
The DG211B/212B analog switches are highly improved
versions of the industry-standard DG211/212. These devices
are fabricated in 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.)
