Precision Monolithic Quad SPST CMOS Analog Switches
DESCRIPTION FEATURES
The DG417B, DG418B, DG419B monolithic CMOS analog 15 V analog signal range
switches were designed to provide high performance On-resistance - R : 15
DS(on)
switching of analog signals. Combining low power, low Fast switcing action - t : 110 ns
ON
leakages, high speed, low on-resistance and small physical TTL and CMOS compatible
size, the DG417B series is ideally suited for portable and 8-pin CerDIP package
battery powered industrial and military applications requiring
BENEFITS
high performance and efficient use of board space.
Widest dynamic ranges
Low signal errors and distortion
To achieve high-voltage ratings and superior switching
Break-before-make switching action
performance, the DG417B series is built on Vishay
Simple interfacing
Siliconixs high voltage silicon gate (HVSG) process.
Reduced board space
Break-before-make is guaranteed for the DG419B, which is
Improved reliability
an SPDT configuration. An epitaxial layer prevents latchup.
APPLICATIONS
Each switch conducts equally well in both directions when
Precision test equipment
on, and blocks up to the power supply level when off.
Precision instrumentation
Battery powered systems
The DG417B and DG418B respond to opposite control logic
Sample-and-hold circuits
levels as shown in the Truth Table.
Military radios
Hi-Rel systems
Guidance and control systems
Hard disk drivers
