DESCRIPTION

Featuring low on-resistance (60 W) 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.

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.

Designed with the Vishay Siliconix PLUS-40 CMOS process

to combine low power dissipation with a high breakdown

The DG308B/309B upgrades are recommended for new

designs.
