DESCRIPTION

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.

To achieve high-voltage ratings and superior switching

performance, the DG417B series is built on Vishay

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

make is guaranteed for the DG419B, 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 DG417B and DG418B respond to opposite control logic

levels as shown in the Truth Table.
