DESCRIPTION

The DG9431 is a single-pole/double-throw monolithic CMOS

analog device designed for high performance switching of

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.
