Vishay Siliconix

Precision Monolithic Quad SPST CMOS Analog Switches

DESCRIPTION

FEATURES

•

15 V analog signal range

The DG417B, DG418B, DG419B monolithic CMOS analog

switches were designed to provide high performance

switching of analog signals. Combining low power, low

leakages, high speed, low on-resistance and small physical

size, the DG417B series is ideally suited for portable and

battery powered industrial and military applications requiring

high performance and efficient use of board space.

On-resistance - R : 15 Ω

DS(on)

Fast switching action - t : 110 ns

TTL and CMOS compatible

MSOP-8 and SOIC-8 package

Compliant to RoHS directive 2002/95/EC

BENEFITS

To achieve high-voltage ratings and superior switching

performance, the DG417B series is built on Vishay

Siliconix’s high voltage silicon gate (HVSG) process. Break-

before-make is guaranteed for the DG419B, which is an

SPDT configuration. An epitaxial layer prevents latchup.

•

Widest dynamic range

Low signal errors and distortion

Break-before-make switching action

Simple interfacing

Reduced board space

Improved reliability

Each switch conducts equally well in both directions when

on, and blocks up to the power supply level when off.

The DG417B and DG418B respond to opposite control logic

levels as shown in the Truth Table.

APPLICATIONS

•

Precision test equipment

Precision instrumentation

Battery powered systems

Sample-and-hold circuits

Military radios

Guidance and control systems

Hard disk drivers
