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.

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.
