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.

Notes:
a. Room = 25 °C, Full = as determined by the operating temperature suffix.
b. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this datasheet.
c. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.
d. Guaranteed by design, not subject to production test.
e. V

= input voltage to perform proper function.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation
of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.
