DESCRIPTION
The DG417B/418B/419B 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.
high voltage silicon gate (HVSG) process. Break-before-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.
To achieve high-voltage ratings and superior switching
performance, the DG417B series is built on Vishay Siliconix鈥檚
The DG417B and DG418B respond to opposite control logic
levels as shown in the Truth Table.
