DESCRIPTION

Featuring low on-resistance (60 ) and fast switching

(130 ns), the DG308A is supplied in the “normally open”

configuration while DG309 is supplied “normally closed”.

Input thresholds are high voltage CMOS compatible.

Designed with the Vishay Siliconix PLUS-40 CMOS process

to combine low power dissipation with a high breakdown

voltage rating of 44 V, each switch conducts equally well in

both directions when on, and blocks up to the supply voltage

when off. An epitaxial layer prevents latch up.

The DG308B, DG309B upgrades are recommended for new

designs.
