Description

TheDG417/418/419 monolithic CMOS analog switches were designed to provide high performanceswitching 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 poweredindustrial and military applications requiring high performance and efficient use of board space.

To achieve high-voltage ratings and superior switching performance, the DG417 series is built on 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.

Each switch  comducts equally well in both directions when on,and blocks up to the power supply level when off.

TheDG417 and DG418 respond to opposite control logic levels as shown in the Truth Table.
