DESCRIPTION
The DG308B, DG309B analog switches are highly improved
versions of the industry-standard DG308A, DG309. 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 DG308B and DG309B
can handle up to ± 22 V input signals. 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 DG308B is a normally open switch and the DG309B is
a normally closed switch. (see Truth Table.)
