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

power, high speed (t

ON

: 25 ns, t

OFF

: 20 ns), the

DG9432/9433/9434 is ideal for portable and battery powered

applications requiring high performance and efficient use of

board space.

The DG9432/9433/9434 is built on Vishay Siliconix鈥檚 low voltage

BCD-15 process. An epitaxial layer prevents latchup.

Break-before -make is guaranteed for DG9432/9433/9434.

Each switch conducts equally well in both directions when on,

and blocks up to the power supply level when off.
