Precision Monolithic Quad SPST 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. Break-
before-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.

Notes:
a. Refer to PROCESS OPTION FLOWCHART.
b. Room = 25 °C, full = as determined by the operating temperature suffix.
c. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation
of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.
