DG419

DG417, DG418, DG419 Vishay Siliconix Precision CMOS Analog Switches DESCRIPTION The DG417, DG418, DG419 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. 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-beforemake 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. The DG417 and DG418 respond to opposite control logic levels as shown in the Truth Table.
