CMOS Analog Switches
DESCRIPTION
The DG417B, DG418B, DG419B 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.
To achieve high-
voltage ratings and superior switching performance, the DG417B series is built on Vishay Siliconix’s high
voltage silicon gate (HVSG) process. Breakbefore-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.
The DG417B and DG418B respond to opposite control logic levels as shown in the Truth Table.
FEATURES ± 15 V analog signal range On-resistance - RDS(on): 15 Ω Fast switching action - tON: 110 ns TTL and
CMOS compatible MSOP-8 and SOIC-8 package Compliant to RoHS directive 2002/95/EC
BENEFITS Widest dynamic range Low signal errors and distortion Break-before-make switching action Simple interfacing Reduced board space Improved reliability
