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.

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.

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

The DG201B is a normally closed switch and the DG202B is

a normally open switch. (See Truth Table.)
