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 (tON: 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.
