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.)

Notes:
a. Room = 25 °C, Full = as determined by the operating temperature suffix.
b. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
c. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.
d. Guaranteed by design, not subject to production test.
e. V
IN
= input voltage to perform proper function.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation
of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.
