Description

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.

To achieve high-voltage ratings and superior switching

performance, the DG417 series is built on 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.

Each switch conducts equally well in both directions

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

off.

The DG417 and DG418 respond to opposite control logic

levels as shown in the Truth Table.
