DG201B/202B

Vishay Siliconix

Improved Quad CMOS Analog Switches

DESCRIPTION

FEATURES

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.

•

22 V Supply Voltage Rating

Pb-free

TTL and CMOS Compatible Logic

Low On-Resistance - r_DS(on): 45 Ω

Low Leakage - I_D(on): 20 pA

Single Supply Operation Possible

Extended Temperature Range

Fast Switching - t_ON: 120 ns

Low Glitching - Q: 1 pC

Available

RoHS*

COMPLIANT

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.

BENEFITS

• Wide Analog Signal Range

•

Simple Logic Interface

Higher Accuracy

Minimum Transients

Reduced Power Consumption

Superior to DG201A/202

• Space Savings (TSSOP)

All devices feature true bi-directional performance in the on

condition, and will block signals to the supply voltages in the

off condition.

APPLICATIONS

• Industrial Instrumentation

•

Test Equipment

Communications Systems

Disk Drives

Computer Peripherals

Portable Instruments

The DG201B is a normally closed switch and the DG202B is

a normally open switch. (See Truth Table.)
