DG211B, DG212B
Vishay Siliconix
Improved Quad CMOS Analog Switches
DESCRIPTION
The DG211B, DG212B analog switches are highly improved
versions of the industry-standard DG211, DG212. 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.)
