DG9431
Vishay Siliconix
Low-Voltage Single SPDT Analog Switch
DESCRIPTION
The DG9431 is a single-pole/double-throw monolithic CMOS
analog device designed for high performance switching of
analog signals. Combining low power, high speed
(tON: 35 ns, tOFF: 20 ns), low on-resistance (rDS(on): 20 Ω)
and small physical size (TSOP-6), the DG9431 is ideal for
portable and battery powered applications requiring high
performance and efficient use of board space.
The DG9431 is built on Vishay Siliconix’s low voltage
BCD-15 process. Minimum ESD protection, per Method
3015.7, is 2000 V. An epitaxial layer prevents latchup.
Break-before -make is guaranteed for DG9431.
Each switch conducts equally well in both directions when
on, and blocks up to the power supply level when off.
As a committed partner to the community and the
environment, Vishay Siliconix manufactures this product
with the lead (Pb)-free device terminations. For analog
switching products manufactured with 100 % matte tin
device terminations, the lead (Pb)-free “-E3” suffix is being
used as a designator.
