DG441/442
Vishay Siliconix
Quad SPST CMOS Analog Switches
DESCRIPTION
The DG441/442 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
Ω,
typ.) with high speed
(t
ON
150 ns, typ.), the DG441/442 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 DG441/442 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.
