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.
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 The DG417 and DG418 respond to opposite control logic
performance, the DG417 series is built on Siliconix’s high levels as shown in the Truth Table.
