The DG441, DG442 monolithic quad analog switches are
designed to provide high speed, low error switching of analog
and audio signals. The DG441 has a normally closed
function. The DG442 has a normally open function.
Combining low on-resistance (50
,
typ.) with high speed
(t
ON
150 ns, typ.), the DG441, DG442 are ideally suited for
upgrading DG201A/202 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 DG441, DG442 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.

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.
