DESCRIPTION

The DG444/DG445 monolithic quad analog switches are

designed to provide high speed, low error switching of analog

signals. The DG444 has a normally closed function. The

DG445 has a normally open function. Combining low power

(22 nW, typ) with high speed (t_ON: 120 ns, typ), the

DG444/DG445 are ideally suited for upgrading DG211/212

sockets. Charge injection has been minimized on the drain for

use in sample-and-hold circuits.

To achieve high-voltage ratings and superior switching

performance, the DG444/DG445 are built on Vishay Siliconix’s

high-voltage silicon-gate process. An epitaxial layer prevents

latchup.

Each switch conducts equally well in both directions when on,

and blocks input voltages to the supply levels when off.
