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.
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.
To achieve high-voltage ratings and superior switching
performance, the DG417 series is built on Vishay Siliconix’s
The DG417 and DG418 respond to opposite control logic
levels as shown in the Truth Table.
