ON
: 120 ns
• Low charge injection
• DG211, DG212 upgrades
TTL/CMOS logic compatible
BENEFITS
Low signal errors and distortion
• Reduced power supply requirements
• Faster throughput
• Improved reliability
• Reduced pedestal errors
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, DG212
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.
Simple interfacing
