DESCRIPTION

The DG411 series of monolithic quad analog switches was

designed to provide high speed, low error switching of

precision analog signals. Combining low power (0.35

mW) with

portable

and

battery

powered

industrial

and

military

applications.

To achieve high-voltage ratings and superior switching

performance, the DG411 series was built on Vishay Siliconix’s

high voltage silicon gate process. An epitaxial layer prevents

latchup.

Each switch conducts equally well in both directions when on,

and blocks input voltages up to the supply levels when off.

The DG411 and DG412 respond to opposite control logic as

shown in the Truth Table. The DG413 has two normally open

and two normally closed switches.
