DESCRIPTION

The DG308B/309B analog switches are highly improved

versions of the industry-standard DG308A/309. 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.

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.

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

The DG308B is a normally open switch and the DG309B is a

normally closed switch. (See Truth Table.)
