DG417/418/419

Vishay Siliconix

Precision CMOS Analog Switches

DESCRIPTION

FEATURES

The DG417/418/419 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

DG417 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): 20 Ω

Available

Fast Switching Action - t_ON: 100 ns

Ultra Low Power Requirements - P_D: 35 nW

TTL and CMOS Compatible

RoHS*

COMPLIANT

MiniDIP and SOIC Packaging

• 44 V Supply Max Rating

BENEFITS

To achieve high-voltage ratings and superior switching

performance, the DG417 series is built on Vishay Siliconix’s

high voltage silicon gate (HVSG) process. Break-before-

make is guaranteed for the DG419, which is an SPDT

configuration. An epitaxial layer prevents latchup.

•

Wide 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.

APPLICATIONS

•

Precision Test Equipment

Precision Instrumentation

Battery Powered Systems

Sample-and-Hold Circuits

Military Radios

The DG417 and DG418 respond to opposite control logic

levels as shown in the Truth Table.
