Specifications of DG419DY-T1-E3/BKN

Lead Free Status / Rohs Status
RoHS Compliant part Electrostatic Device
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-before-
make 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.
