DESCRIPTION
The DG201B/202B analog switches are highly improved
versions of the industry-standard DG201A/202. 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 DG201B and DG202B can handle
up to "22-V input signals, 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 voltages in the
off condition.
The DG201B is a normally closed switch and the DG202B is
a normally open switch. (See Truth Table.)
