DG417B/418B/419B

Vishay Siliconix

Precision Monolithic Quad SPST CMOS Analog Switches

DESCRIPTION

FEATURES

The DG417B/418B/419B 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.

•

15 V Analog Signal Range

Pb-free

On-Resistance - r_DS(on): 15 Ω

Fast Switching Action - t_ON: 110 ns

TTL and CMOS Compatible

Available

RoHS*

COMPLIANT

MSOP-8 and SOIC-8 Package

BENEFITS

•

Widest Dynamic Range

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.

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.

APPLICATIONS

•

Precision Test Equipment

Precision Instrumentation

Battery Powered Systems

Sample-and-Hold Circuits

Military Radios

The DG417B and DG418B respond to opposite control logic

levels as shown in the Truth Table.
