DESCRIPTION
The DG9432/9433/9434 is a dual single-pole/single-throw
monolithic CMOS analog switch designed for high
performance switching of analog signals. Combining low
The DG9432/9433/9434 is built on Vishay Siliconix’s low voltage
BCD-15 process. An epitaxial layer prevents latchup.
Break-before -make is guaranteed for DG9432/9433/9434.
power, high speed (tON
:
25 ns, tOFF
:
20 ns), the
DG9432/9433/9434 is ideal for portable and battery powered
applications requiring high performance and efficient use of
board space.
Each switch conducts equally well in both directions when on,
and blocks up to the power supply level when off.
